This post will look at how difficult it is to learn Spanish for an English speaker.
Spanish is often said to be one of the easiest languages to learn, though this is somewhat controversial. Personally, I’ve been learning it off and on since age six, and I still have problems, though Spanish speakers say my Spanish is good, but Hispanophones, unlike the French, are generous about these things.
It’s quite logical, though the verbs do decline a lot with tense and number, and there are many irregular verbs, similar to French.

Nevertheless, Romance grammar is much more regular than, say, Polish, as Romance has junked most of the irregularity. Spanish has the good grace to lack case, spelling is a piece of cake, and words are spoken just as they are written. However, there is a sort of case left over in the sense that one uses different pronouns when referring to the direct object (accusative) or indirect object (dative). Spanish is probably the most regular of the Romance languages, surely more regular than French or Portuguese, and probably more regular than Italian or Romanian.

One good thing about Spanish is that Spanish speakers are generally grateful if you can speak any of their language at all and are very tolerant of mistakes in L2 Spanish speakers.
Nevertheless, Hispanophones say that few foreigners end up speaking like natives. Part of the reason for this is that Spanish is very idiomatic and the various forms of the subjunctive make for a wide range of nuance in expression. Even native speakers make many mistakes when using the subjunctive in conditional sentences. The dialects do differ quite a bit more than most people say they do. The dialects in Latin America and Spain are quite different, and in Latin America, the Argentine and Dominican dialects are very divergent.
Spanish gets rated 2.5, fairly easy.
