Konjugacije na -IM

Same idea as the other two groups, new vowel. Once you know raditi gives radim, the rest is fixed:

The "they" form is -e: rade, vide, uče, vole, žive. Compare it with the -am group's gledaju and the -em group's jedu, and you have all three plurals in one glance.

Here's the part that trips people up. Most verbs in this group end in -iti, which is a helpful signpost — but a handful end in -eti and still belong here: videti → vidim, voleti → volim, živeti → živim. That -e- in the infinitive tempts you toward the -em group, and it's wrong. Nothing to do but know them.
