sequor

Sequor, sequi, secutus sum is third conjugation and deponent: passive in form, active in meaning. Secuti sunt is "they followed", never "they were followed", and the infinitive is sequi, not sequere. It takes a plain accusative for whatever is being followed.

The participles are the place people trip. Sequens, "following", is active and looks normal. Secutus is the only past participle it has, and it is active too, "having followed" - a deponent perfect participle does not behave like a passive one, which means Latin quietly gives you something the language otherwise lacks. Note also secundus, rank 396, which is literally "following" and gets to "second" and "favourable" from there; a secundus ventus is a wind going your way. Family: consequor, persequor, prosequor, obsequium, sequax. English sequel, sequence, consecutive, persecute, obsequious, second, suit, sue and ensue.
