Pronunciation
Forms
θᾰ́λλω (thállō) [1] Laconian σάλλω, Aeolic and Doric perfect τέθᾱλα.[2][3]
Etymology
It is inherited from Proto-Indo-European *dʰalh₁- (“to well up, sprout”), the reconstruction of the LIV, which Beekes doubts.[4][5][1] The only certain cognates are in Albanian and Armenian: Albanian dal (“to sprout”), which may continue a present formed like θάλλω, and Old Armenian դալար (dalar, “green, fresh”), compared directly with θαλερός (thalerós).[5][6][1] Clackson objects that the suffix is productive in Armenian and that the meaning may have developed separately.[5]
Wiktionary adds Celtic words for “leaf” such as Welsh dalen, but Beekes thinks the Celtic material is best kept apart.[1][5]
Ancient writers derived it from a verb “to feed”, since what is fed grows.[7]
Earliest recorded meaning
Homer has only the perfect participle τεθηλώς with present sense, “flourishing, rich”: a back rich with fat in the Iliad (9.208), and leafy trees in the Odyssey.[3][8] The present θάλλω is first found in Hesiod's Works and Days and the Homeric Hymn to Demeter.[5][3]
Semantic evolution
The verb is used first of plants and land: to sprout, flourish, bear fruit, be in bloom.[2][3] From the Archaic poets on it is used of people, cities and states of life: Hesiod speaks of flourishing Peace, Pindar of thriving happiness, and Sophocles of a father who prospers.[3][2] In tragedy it can also be said of evils that keep growing, as a disease that is always fresh in Sophocles' Philoctetes.[3] The Hippocratic writers use it of a swollen spleen.[3]
The Septuagint uses it of plants sprouting and of a fire that rages.[9]
It survives as Modern Greek θάλλω (thállo), a learned word taken from the ancient one.[10]
