To give a general tip based on what Labhras has already said, note that some dictionaries (De Bhaldraithe), the verb form is given in the first person present tense. Not all dictionaries follow this (O Donaill, for example, does not), but just be aware of it when you are looking up words. A big part of using an Irish dictionary well (or any language for that matter) is learning how to decipher and contextualize what it’s telling you, which gets easier as your knowledge of the language increases, of course. Good luck!
