+ '''cōgō''' (present infinitive cōgere, perfect active coēgī, supine coāctum); third conjugation^(Wiktionary)
+ An inscription of the Arval Brethren has ''COGVIT'' for ''cōgit''.^(Lewis & Short 1879)
+
+ ==Etymology==
+ It is contracted from ⟨*co-agō⟩, formed [[af|la|con-|agō|t2=to drive]], “drive together”.^(OLD 2012)^(TLL)^(Lewis & Short 1879)^(Wiktionary) The simple verb continues [[itc-pro|*ag-e/o-|t=to do, act]], from [[ine-pro|*h₂eǵ-|t=to drive, lead]].^(de Vaan 2008) Compare [[grc|ἄγω|tr=ágō|t=to drive, lead]] and [[sa|अजति|tr=ájati|t=drives]].^(de Vaan 2008)
+
+ ==Earliest recorded meaning==
+ Plautus has ''ut sibi latrōnēs cōgerem et cōnscrīberem'', “to collect and enlist mercenaries for him”.^(OLD 2012)^(Köbler 2010)
+
+ ==Semantic evolution==
+ The first sense is “to drive together”: cattle (''Tītyre, cōge pecus'' “Tityrus, round up the flock”), people, and troops, so “to assemble, muster”, “to raise” an army or fleet and “to convene” the senate or an assembly.^(OLD 2012) It is used of gathering crops and collecting money, and ''agmen cōgere'' is “to bring up the rear”.^(OLD 2012) From “bring into a mass” come “to compress, condense, abridge”, “to thicken, curdle, congeal” and “to full” cloth.^(OLD 2012)
+
+ Applied to persons it means “to drive” somewhere, “to reduce” to a condition (''in ōrdinem cōgere'' “to bring to order”) and above all “to compel, force”, of people and of circumstances (''necessitāte cōgī'').^(OLD 2012)^(Lewis & Short 1879) In argument it means “to prove conclusively”.^(OLD 2012)
+
+ ==Timeline==
+ * c. 250–184 BC – Plautus uses it of raising mercenaries and of compulsion (''nisi necessitāte cōgar'').^(OLD 2012)^(Köbler 2010)
+ * 190–159 BC – Terence uses it of collecting money: ''quasi talenta ad quīndecim coēgī''.^(OLD 2012)^(Köbler 2010)

+ * c. 50 BC – Caesar: ''coāctīs omnibus cōpiīs'', “with all his forces assembled”.^(OLD 2012)^(Köbler 2010)
