razi

One root, nothing inside it. Razi is raz- plus the infinitive -i, and that is the end of the analysis. It came from French raser in a single piece. Two syllables, "RAH-zee", with the stress on the first as always.

Reflexive by default in practice. In Esperanto you shave something: a beard, your hair, a leg. When the object is yourself, you say it: mi razas min, I shave. Leaving the object out (mi razas) is understood but reads as unfinished, in the way that English "I am shaving" is fine and Esperanto's bare verb is slightly less so. The reflexive article covers si and sin, and this verb is a good one to practise on because the third person is where learners slip: li razas sin is he shaves himself, li razas lin is he shaves some other man, and the difference is one letter with a very different scene behind it.

The cutting verbs, distinguished. Razi takes hair off flush with the skin. Tondi is to clip or shear, leaving length behind, so a sheep and a hedge are both tondita and a chin is razita. Tranĉi is the general cut, with a blade, through something. Haki is to chop. Four verbs, four instruments, and Esperanto keeps them apart more strictly than English does, which uses "cut" for all of them and lets context sort it out.

The tool and the trade. Razilo is a razor, built with -il- exactly as hakilo is: the shaving tool. Razisto is a barber, though barbiro is the borrowed word you will more often see on a shop sign, and razkremo is shaving cream. Nerazita is unshaven. And there is a figurative use worth knowing: razi a building or a town means to raze it, to take it down to ground level, exactly as in English and from exactly the same Latin verb.
