S is one of the most versatile tiles in English-language Scrabble because it can be appended to many words to pluralize them (or in the case of most verbs, convert them to the third person singular present tense, as in the word PLUMMETS), Alfred Butts included only four S tiles to avoid making the game "too easy". Q is considered the most troublesome letter, as almost all words with it also contain U, a similar problem occurs in other languages like French, Dutch, Italian, and German. J is also difficult to play due to its low frequency and a scarcity of words having it at the end. C and V may be troublesome in the endgame, since no two-letter words with them exist, save for CH in the "Collins Scrabble Words" lexicon.
