• In English, the verbs go and come in the senses of physical motion are often used in relation to the listener. If Alice calls Bob and asks him if he is on his way to her party, he would say, "I'm coming."

However, in Japanese, the verbs 行く (iku, “to go”) and 来る (kuru, “to come”) are used in relation to the speaker. If Alice calls Bob and asks him if he is on his way to her party, he would instead say, 「行きます」 (Ikimasu, "I'm going").

• The more common form, いく (iku), has a slightly irregular conjugation than a regular godan verb. Its perfective and conjunctive constructions are 行(い)った (itta) and 行(い)って (itte) respectively, instead of the expected いいた (iita) and いいて (iite). The literary form, ゆく (yuku), conjugates regularly as 行(ゆ)いた (yuita) and 行(ゆ)いて (yuite).
• As an auxiliary, it is more commonly spelled in hiragana. It can also be colloquially shortened to てく (-teku).

• (antonym(s) of “to come”): 来(く)る (kuru)

• いらっしゃる (irassharu) (honorific)
• 参(まい)る (mairu) (humble)
