Etymology and origin of the Latin word introrsum
Etymology tree
From the same root
Forms
intrōrsum (not comparable)[1] It is also found as introrsus, intrōsum and intrōsus,[2][3] and uncontracted as introversus (introvorsus).[3]
Etymology
It is from Latin intrō1 (“inside”) + versus2 (“towards”), contracted.[2][4][5][1] De Vaan explains ⟨intrō⟩ as an old ablative of Proto-Indo-European *h₁en-tero- (“situated within”), derived from Proto-Indo-European *h₁en (“in”).[6]
Earliest recorded meaning
Köbler records it from Lucretius,[7] who writes of breath of which part is driven out and part withdraws inwards;[2] Varro has trees leaning inwards.[2]
Semantic evolution
It means inwards, to the inside: Livy has the enemy taken into the middle of the camp, and Caesar a wooded hill that could not easily be seen into.[2][5][8] It also means on the inside or within: Sallust says that Bithynia is the first part of Asia, going inwards, and Livy reports tribunes shouting that there was no strength within.[2][8]
Figuratively it is inwardly, at heart: Seneca tells someone to hide grief inwardly, says that things shine outside but are wretched within, and calls a man happy inwardly.[2][5][8] Horace writes of a man whom his whole household sees to be foul within,[5] and Ovid of tears welling up inside.[2][5] British Medieval Latin also uses it for inwardly or privately.[9] English formed introrse from introrsus in 1831.[10]
