I notice that among the available words there’s a clear set related to camera lenses. In photography you commonly hear “zoom lens,” “telephoto lens,” “macro lens” and “fisheye lens.” This group stands out as a set of four related terms.

After the camera lenses have been solved, we have 12 words remaining. In our earlier attempt we tried a contact information grouping with CALL, NUMBER, ADDRESS, and EMAIL, but that was rejected. Notice that among the remaining words we have both CALL and NAME, even though both are common components of contact details. Standard contact information is usually presented with a person's NAME, ADDRESS, EMAIL, and PHONE NUMBER. Since “CALL” is a verb and may not fit as well in a list of nouns, a natural group that appears among the remaining words is the set that includes NAME, ADDRESS, EMAIL, and NUMBER.

I see that several remaining words describe a confidential or intimate aspect. In particular, SECRET, PRIVATE, PERSONAL, and INNER all suggest something kept hidden or internal.

We’ve already used the following words in three groups: • Group 1 (Currencies): DOLLAR, POUND, WON, STERLING • Group 2 (Things “private” or “internal”): SECRET, PRIVATE, PERSONAL, INNER • Group 3 (Words that can describe something “important”): MAJOR, KEY, PRINCIPAL, CRITICAL That leaves us with eight words originally but now only four remain unused: • WING, SOLDIER, NICKEL, BILL Observing these four, one can note that two of them (WING and BILL) are parts of a bird. In fact, “bill” is the beak of a bird and “wing” is self‐explanatory. In some word puzzles the remaining set turns out to be “chicken” things—forming familiar phrases like CHICKEN WING. 
While “SOLDIER” and “NICKEL” seem less obviously avian at first glance, they can tie in via playful language. For example, “chicken soldier” can be a whimsical term (it appears occasionally in children’s literature or playful slang), and “chicken nickel” is a pun on “nickel” meaning a small coin or “chicken feed.” 
Thus the four words – WING, SOLDIER, NICKEL, BILL – combine with “CHICKEN” to yield common or punny phrases (CHICKEN WING, CHICKEN SOLDIER, etc.), making them a valid Connections group.

The remaining words are MAJOR, KEY, PRINCIPAL, and CRITICAL. These words are commonly paired with "ROLE": as in MAJOR ROLE, KEY ROLE, PRINCIPAL ROLE, and CRITICAL ROLE.

Examining the available words, I noticed a potential pattern with types of underwear. "BRIEF" is a style of underwear, as is "BOXER" (or boxer briefs), "THONG" is a well-known underwear style, and "HIPSTER" describes a cut of underwear as well. This group of four words consistently fits into the category of underwear types.

Looking over the remaining words, I see a clear connection in four words that are all parts of a toilet tank. In a toilet tank you commonly find a FLOAT (float ball), a HANDLE (flushing lever), a FLAPPER (the rubber valve), and a CHAIN (which connects the handle to the flapper). This connection is well-known in puzzles.

Among the available words, I noticed that FREEZE, MELT, VAPORIZE, and CONDENSE all describe processes of phase changes in matter, specifically with water. This common link makes them a strong candidate for a related group.

We have already identified three groups: • Group 1: FREEZE, MELT, VAPORIZE, CONDENSE • Group 2: SUB, ALTERNATE, BACKUP, COVER • Group 3: FANTASY, HERO, HONEY, SOMEDAY That leaves us with four words yet to be grouped: COPPER, HACK, SHRINK, SUIT. Looking at these remaining words, an alternate reading of each suggests a slang term for a type of professional. “COPPER” is common slang for a policeman, “HACK” is used to refer to a mediocre writer (or journalist), “SHRINK” is slang for a psychologist or psychiatrist, and “SUIT” is a colloquial reference to a businessperson (or sometimes lawyer) – the archetypal “dress-for-success” figure. All four thus point to common occupations via slang terms. This makes for a neat, unified category.

The remaining words are RICE, WORD, BLONDE, and POOL. I looked for a common word that combines with each to form familiar terms. For instance, “GOLDEN RICE” is a well‐known variety (also linked to biofortification), “GOLDEN WORD(s)” can refer to a prized saying, “GOLDEN BLONDE” is a common descriptor for a hair color, and “GOLDEN POOL” is a name sometimes given to a beautiful or sunlit swimming pool. Considering these compounds, I believe the common theme is that they can all follow the word GOLDEN.

I noticed that some of the available words are names of American automotive brands. In particular, DODGE, FORD, LINCOLN, and RAM are all car or truck brands—with RAM being the truck division originally part of Dodge, and LINCOLN serving as Ford’s luxury division. They clearly form a related group.

I’ve identified that the remaining eight words split into two groups. One group forms foods typically served with CHICKEN, and the final group contains names of NHL teams. Specifically, the words SENATOR, DUCK, STAR, and FLYER correspond to NHL teams: • Ottawa Senators (SENATOR) • Anaheim Ducks (DUCK) • Dallas Stars (STAR) • Philadelphia Flyers (FLYER) This grouping is clear.

I noticed that several available words can all follow the word "KING" to form well-known phrases: KING KONG, KING TUT, KING COBRA, and KING CAKE. These four words all share a common connection when paired with "KING". Therefore, I believe these are the related words you are looking for.

I've noticed that several remaining words are tied to iconic Eddie Murphy roles. DOLITTLE represents the film "Doctor Dolittle," AKEEM is from "Coming to America," DONKEY is his character in "Shrek," and FOLEY is Axel Foley from "Beverly Hills Cop." This clearly forms a related connection through Eddie Murphy's movie roles.

Looking at the remaining words, I see that ZIP, BARREL, FLY, and RACE can all be used as verbs meaning “to move quickly.” You can zip along, barrel along, fly along, or race along – each implying rapid movement. This connection is clear and distinct.

Considering the male animal connection again, I now suspect that the intended group isn’t the one we previously tried (which included STAG), but rather a slightly different set. Notably, “BILLY” (as in billy goat), “RAM” (male sheep), “BUCK” (a male deer or goat), and “JACK” (as in jackass for a male donkey) all denote male animals. This seems like a solid grouping.

I noticed a set of words that can all be used to describe “nonsense.” “Bull” (as in “bullshit”), “baloney” (a synonym for foolishness), “bunk” (informal for “nonsense”), and “rubbish” (another term for nonsense) naturally form a group. This fits the clue structure for the Connections game.

I noticed that the words NAP, WALK, FISH, and TAIL can all follow the word "CAT" to form common terms: CATNAP, CATWALK, CATFISH, and CATTAIL. This connection seems solid and fits the pattern of the Connections game.

I noticed that among the available words, four of them (ROLLER, CARRY-ON, HARD-SHELL, DUFFEL) refer to types or features associated with luggage. “ROLLER” suggests rolling luggage, “CARRY-ON” is the bag allowed on planes, “HARD-SHELL” is a style of suitcase, and “DUFFEL” is a travel bag. This consistent travel and luggage connection makes them a promising set.

The remaining words are BRIGHT, BOUNCY, MERRY, and SUNNY. They all serve as adjectives describing a cheerful or lively mood. This consistent theme indicates they form the last group.
