Đó là lý do vì sao
/dɔː laː lǐ˧˧ ɗɔ˧˧ vi˧˧ ʂaːw˧˧/
VI
That is why
Đó là lý do vì sao tôi không thể đến dự buổi họp.
That is why I cannot attend the meeting.
Etymology
This is a fixed phrase in Vietnamese, formed by combining the demonstrative 'đó' (that), the copula 'là' (is), the noun 'lý do' (reason), and the interrogative 'vì sao' (why). It has been used this way in colloquial and formal Vietnamese for centuries.
Memory Aid
Break the phrase down: 'Đó là' = that is, 'lý do' = reason, 'vì sao' = why, so it means that is the reason why, shortened to that is why.
