Romanian is a Romance language, so if you know Spanish, Italian, or French much of the vocabulary will feel familiar. The twists are its retained noun cases, its definite article attached to the end of the word, and a layer of Slavic vocabulary. A sensible reading order lets you lean on the familiar while working through what is genuinely new. Keep in mind that books build reading and grammar; conversational fluency still needs speaking practice.
Start with a full course, add targeted grammar and verb references, then read real Romanian to lock it all in.
Start with a course
Begin with Teach Yourself Romanian, a complete beginner course that builds pronunciation, dialogues, and core grammar in a steady arc. Colloquial Romanian is an excellent parallel course, heavy on everyday conversation and audio, so use it to reinforce the same foundations from a different voice. Keep Romanian Phrasebook & Dictionary on hand for quick vocabulary and travel-ready phrases.
Drill grammar and verbs
Once you can handle simple sentences, work through Romanian, an essential grammar by Ramona Gönczöl-Davies, a clear reference to cases, articles, and word order. 501 Romanian Verbs is your conjugation workhorse, indispensable for a language whose verb forms carry so much meaning. For a deeper, Romanian-authored treatment, Gramatica limbii române pentru străini addresses the exact problems foreign learners hit, and Exerciții de vocabular by Gheorghe Doca gives structured vocabulary practice.
Read Romanian literature
With grammar in place, consolidate through the classics. Amintiri din copilărie by Ion Creanga, warm childhood memoirs, is a traditional first real read. Moromeții by Marin Preda and Maitreyi nunta în cer by Mircea Eliade then stretch you into full literary prose, growing vocabulary and giving you the rhythm of native writing. Finishing whole books is what turns study into fluency in reading.
These books will carry your reading and grammar a long way, but speaking Romanian needs real conversation. Add a tutor or exchange partner and follow the full path in order.
