Is Catalan the same as Spanish?

Key Grammatical and Lexical Differences

Although both Catalan and Spanish have common ancestors and reflect their shared Romance origins, several key grammatical differences exist. One crucial distinction is the use of certain verb tenses and conjugations. Some Catalan verb conjugations resemble Italian and French more closely than Spanish. Likewise, the Catalan language incorporates the use of third-person object pronouns before a verb, similar to French, whereas Spanish uses the pronoun after the verb.
