Helping Verbs: …ていく and …てくる

Using motion verbs （行く、来る） with the te-form

<div class='writeup-body'>This grammar construction is a mix of the conjunction particle て, and the verb 行（い）く 'to go'. To use this grammar point, you will need to attach て to any verb, and then follow it with いく. This nuance is usually that '(A) happened and then went', or 'will happen, and then go'. In other words, it will depend on whether いく is in present, or past tense.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>今日（きょう）はうちで食（た）べていく？</div><div class='writeup-example--english'>Do you want to go and eat at my place tonight? (Literally 'will you', but comes across more as an invitation in casual Japanese)</div></li><li class='writeup-example'><div class='writeup-example--japanese'>今晩（こんばん）は雨（あめ）が降（ふ）ると聞（き）いたから、傘（かさ）を持（も）って行（い）った。</div><div class='writeup-example--english'>Because I heard that it was going to rain tonight, I took an umbrella.</div></li></ul>ていく can be used when representing time, or when representing a physical place. When representing a physical place, it is more likely that the kanji structure, 行（い）く will be used. However, this is not a set rule, and depends on the writer. When used in relation to time, the nuance is usually that something has already started/is about to start, and then will continue to progress in the same way.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>毎日（まいにち）ゴルフの練習（れんしゅう）をしたらだんだんと上手（うま）くなっていく。</div><div class='writeup-example--english'>When you practice golf everyday, you will gradually get better.</div></li> </ul>This is the opposite of てくる, which indicates that something has finally reached a certain state, after progressing in that way for some time.<div class='writeup-funfact'><div class='funfact-header'>Fun Fact</div>When compared to English, ていく is very similar to the phrase 'to go on to (A)', in relation to time. It focuses on the fact that the speaker is required to make some type of journey to arrive at a specific point. For example, 'She went on to become a doctor after university'.</div></div>
