THREE LETTER SCRABBLE WORDS
BRR – the way you tell people that it’s super chilly and the way you tell your WWF opponents that you don’t care what they think of you.
CWM – pronounced “koom,” it’s another name for a “cirque,” which is a bowl-shaped mountain basin often containing a lake.
HMM – accepted (in addition to “hm”) as a sound of contemplation. When you’re thinking just a wee bit harder, it’s “hmm” instead of “hm.”
NTH – having the quality of being the last in a series of infinitely increasing or decreasing values. (As in, “the nth degree.”)
PHT – an interjection used to signify mild annoyance or disagreement.
SHH – also accepted (in addition to “sh”) as a means of urging someone to be quiet.
TSK – an interjection often used in quick repetition (see “tsks,” “tsktsk” and “tsktsks” below) to express contempt or disdain.
FOUR LETTER SCRABBLE WORDS
PFFT – an interjection used to express that something is dying or fizzling out.
PSST – an interjection used to attract someone’s attention.
CWMS – the plural form of the word above
TSKS – plural of “tsk.”
FIVE LETTER SCRABBLE WORDS
CRWTH – pronounced “krooth,” it’s an ancient Celtic musical instrument. Also called a "crowd."
PHPHT – this one presents a troubling case. Its playability appears to be legitimate, but its definition remains elusive. It is either, like “pht,” an interjection expressing mild anger or annoyance, or a shortened version of phenolphthalein (pronounced fee-nawl-thal-een), which is a colorless crystalline compound used in medicine as a laxative and chemistry as an indicator.
SIX LETTER SCRABBLE WORD
CRWTHS – more than one crwth.
TSKTSK – see “tsk” above.
SEVEN LETTER SCRABBLE WORD
TSKTSKS – See “tsk” and its many variations above. Tsktsks is the longest word in the English language with no vowels but its play in WWF is only possible should you elect to use a blank tile as the second ‘K,’ since there is only one ‘K’ tile per game.
