phrasal adjective

[chainsawriot]

I was wondering whether or not you would consider (attributive) phrasal adjectives as single words.

For example: Six-sided (box), man-eating (shark), one-way (street)

The way a lot of us play in English (other languages don't use hyphens that much) is that hyphenated words are valid if they appear in some reliable dictionary. According to this, the examples you give would all be valid:

https://www.collinsdictionary.com/dicti ... /six-sided
https://www.collinsdictionary.com/dicti ... man-eating
https://www.merriam-webster.com/dictionary/man-eating
https://www.collinsdictionary.com/dicti ... sh/one-way
https://www.merriam-webster.com/dictionary/one-way

The game even gives the valid example of "merry-go-round" in the English rules linked from the Just One BGA page itself, and we can see that it's also in the dictionary:
https://www.collinsdictionary.com/dicti ... y-go-round
https://www.merriam-webster.com/diction ... y-go-round

A proper noun (Sherlock, Lego), compound word (merry-go-round), number (007),
onomatopoeia (Riiing), acronym (FBI), or special character ($) are all considered
to be valid clues.

Ah, that's an addition which isn't in the 2018 rules which were previously linked. (Although as one pedant to another, these new rules have a copyright date of 2023 so they might not have come into force yet ).
