〜なくちゃ・〜ないと (~nakucha / ~nai to) — casual "must"

Something you simply have to do — the "I've got to" you say to a friend or to yourself.

Formula (सूत्र ढाँचा)

Verb Vない [ない] + なくちゃ

Verb Vない + と

Grammar rule (व्याकरण नियम र परिभाषा)

When to use it

You hear it constantly when people talk to themselves or to friends.

Meaning

「〜なければならない」is long, so in speech people say 「〜なくちゃ」or 「〜ないと」.

How to attach

The nice part is that the 「いけない」at the end is usually dropped and the sentence just stops there: 「もう帰らなくちゃ」= I've really got to go now.
「〜なきゃ」is the same thing.

Watch out

In formal situations, say 「〜なければなりません」.

Examples (उदाहरणहरू)

もう帰らなくちゃ。

もうかえらなくちゃ。

I've got to head home now.

How it is built (कसरी बन्यो) 帰る (to go back) → ない-form 帰らない → drop ない, add なくちゃ → 帰らなくちゃ. The いけない that would follow is left unsaid.

来月、国にお金を送らないと。

らいげつ、くににおかねをおくらないと。

I have to send money home next month.

How it is built (कसरी बन्यो) 送る (to send) → ない-form 送らない → add と straight to it → 送らないと = I can't get away with not sending it (= I must send it).

明日は早く起きなくちゃいけない。

あしたははやくおきなくちゃいけない。

I have to get up early tomorrow.

How it is built (कसरी बन्यो) 起きる (to get up) → ない-form 起きない → drop ない, add なくちゃ → 起きなくちゃ → here いけない is said too, so the meaning is a little stronger.
