지금 갈게요.

The phrase '지금 갈게요' (jigeum galgeyo) in Korean is a combination of two words: '지금' (jigeum), meaning 'now,' and '갈게요' (galgeyo), which is the future tense form of the verb '가다' (gada), meaning 'to go.' '지금' (jigeum) is a native Korean word that has been in use for a very long time to denote the present moment. Its etymology doesn't involve complex historical linguistic shifts, rather it has remained relatively stable in its form and meaning. '가다' (gada) is also a fundamental native Korean verb. Its root form '가-' is combined with the honorific/polite ending '-시-' (optional, for higher respect) and then the future tense/volitional ending '-을게요' or '-ㄹ게요' (depending on whether the verb stem ends in a consonant or vowel, respectively). In the case of '가다' (which ends in a vowel), it becomes '갈게요.' This ending also carries a nuance of expressing the speaker's intention or promise to perform the action. Therefore, '지금 갈게요' literally translates to 'I will go now' or 'I am going now,' and it conveys the immediate intention or action of departing. The phrase is a direct and common way to express that one is about to leave or depart immediately, often used in casual and semi-formal contexts.
