A very handy item to have is a Latvian spelling dictionary. It gives most forms for most verbs (mine has an odd blind spot of skipping reflexive verbs), nouns and other parts of speech. When you’re just starting to learn verbs, there’s no better way to determine the conjugation, since the majority require knowing both past and present.
My spelling dictionary, called Latviešu valodas pareizrakstības vārdnīca skolām, is published by Jumava and available online from Jānis Roze (jr.lv).
[I love Jānis Roze. They’re fantastic and will ship to the US cheaply and efficiently. Also, their stores are wonderful.]
