Forms
fessus (feminine fessa, neuter fessum, comparative fessior, superlative fessissimus); first/second-declension adjective[1]
Etymology
It is probably in origin a participle of fatīscō (“to split; to grow weary”), with its vowel taken from dēfessus (“worn out”) and kept apart from fassus, the participle of fateor (“to admit”).[2][3] De Vaan explains that ⟨*dē-fat-to-⟩ regularly gave dēfessus, from which the simple adjective was later detached; behind the family he sets a noun ⟨*fatis⟩ “exhaustion”, kept in affatim (“sufficiently”).[4] He finds Walde's root Proto-Indo-European *dʰH- (“to vanish”) gratuitous and knows no cogent further etymology,[4] though Wiktionary and Köbler cite it.[1][5]
Earliest recorded meaning
De Vaan dates it from Varro,[4] who writes that bees hold up their king when he is fessus.[2] Köbler first records it in Cicero.[5]
Semantic evolution
Fessus is “tired out, weary, exhausted”, of people and beasts, of strength, and of travellers, ships and spent winds at the end of their course (Ovid).[2][6][1] It is “weakened” by wounds, disease or hardship (Cicero: fessum inediā fluctibusque, “worn out by hunger and the waves”), “feeble” with age, “exhausted” by war (Cicero of the Veientes), and of things “worn out”.[2][1] It is also “weary in mind, dispirited” (Livy: fessus metū ac labōre mīles), and “sick of” something (Cicero: plōrandō fessus sum, “I am tired of weeping”).[2]
Church Latin glosses it “weary”.[7]
