Latin/Sic and Sicut
What is the difference between sic and sicut?
The basic difference is that, in most uses, "sic" is an adverb (modifying an adjective, adverb, or verb) and "sicut" is a conjunction (initiating a subordinate clause containing a verb).
Examples of "sic" as an adverb:
1) Caesar sic dixit. Caesar spoke thus.
2) Mare sic altum erat ut Caesar submergeretur. The sea was so deep that Caesar drowned.
Examples of "sicut" as a subordinating conjunction:
1) Ars longa est, sicut poeta dixit. Art is long, as the poet said.
2) Ille nunc est sicut eram. That man is now as I used to be.
3) Vita brevis est, sicut apud nos [est]. Life is sort, as [it is] among us.
Sometimes "sicut" is used elliptically, that is, with the verb not expressed, but
implied, as in example 3 above.
