How to say "arabic" in Japanese

• アラビア語アラビアご
  nounCovers 'Arabic' as the language itself. Not an everyday word, but the name to use — when saying that you study or speak Arabic — rather than the colloquial アラブ語.
  彼女かのじょはアラビア語ごが少すこしわかる。↗

  She speaks a little Arabic.
• アラブ語アラブご
  nounAlso names the Arabic language, but it is a colloquial variant: you may hear it in casual conversation, yet アラビア語 is the word you want for writing. Seldom the word to choose.

Both words translate 'Arabic' only in its language sense, so the choice is one of register, not meaning: make 「アラビア語」 your default, and treat 「アラブ語」 as a colloquial variant heard in casual speech.
