私は絵を描きます

The sentence is composed of basic Japanese vocabulary and grammar. '私' (watashi) is a common first-person pronoun. '絵' (e) is a noun for 'picture'. '描きます' (kakimasu) is the polite present/future form of the verb '描く' (kaku), meaning 'to draw' or 'to paint'. The particles 'は' (wa) and 'を' (o) serve grammatical functions to indicate the topic and direct object, respectively. The origins of these individual words can be traced back through various periods of Japanese linguistic development, with many core vocabulary items having roots in Old Japanese and some influence from Chinese characters (Kanji) introduced centuries ago.
