No, Turkish is not a Romance language.
Romance languages evolved from Vulgar Latin, the spoken language of the Roman Empire. These languages include Spanish, French, Italian, Portuguese, and Romanian. Turkish, on the other hand, belongs to the Turkic language family, which has a different origin and linguistic structure.
While Turkish has had contact with Romance languages through historical interactions (for example, some loanwords exist), this doesn't make it a Romance language. The core vocabulary, grammar, and phonology of Turkish are fundamentally different from those of Romance languages. As the provided reference suggests, Turkish shares grammatical features with Balkan languages like Romanian, not because of a Romance connection, but due to geographical proximity and linguistic influence within the Balkan region. This is an example of a linguistic area or Sprachbund.
In summary, Turkish and Romance languages come from separate language families and have distinct origins and linguistic features.
