tetricus

Etymology
. The hypothesis presented by Lewis and Short that it is from  seems to be based on the assumption that this word shows monophthongization of an original diphthong ae to the long vowel ē, but that is contradicted by a number of examples of the first syllable scanning short in poetry.

Adjective

 * 1) forbidding, harsh, crabbed, gloomy, sour, stern, severe
