- 1Superlative of thin.

Among all the samples on the table, this sheet of paper was easily the thinnest.
Note
A regular superlative with one spelling trap: the final n doubles before -est, just as it does in thinner, because thin ends in a single vowel followed by a single consonant. Short adjectives like this take the suffix rather than most, so "most thin" sounds stilted in ordinary use. The form carries every sense of thin: the thinnest sheet, the thinnest runner, the thinnest soup, the thinnest crowd.
