〜っぱなしだ (~ppanashi da) — left ~ / ~ non-stop

Something left undone that should have been finished, or a bad state going on without a break — with a note of complaint.

Formula (सूत्र ढाँचा)

Vます [ます] + っぱなし + だ／で／の N／にする

Grammar rule (व्याकरण नियम र परिभाषा)

When to use it

Coming home from an eight-hour convenience-store shift you say: 「八時間立ちっぱなしで、足がパンパンだ」— standing and standing, not one minute sitting.

Meaning

First use: 「電気をつけっぱなし」— you turned the light on, should have switched it off, but left it on.
Second use (N1): a state going on continuously, without a break — 「立ちっぱなし」, 「負けっぱなし」(losing and losing), 「言われっぱなし」(only getting told off, no chance to answer back).
Both uses carry a complaint: 'more than normal, this isn't right'.

How to attach

Drop 「ます」from the ます-stem and add 「っぱなし」: 立ち + っぱなし
In a sentence it appears as 「〜っぱなしだ」「〜っぱなしで、」「〜っぱなしの N」「〜っぱなしにする」.

Versus what you know

N3You learned 「電気をつけっぱなし」(the first use); N1 adds the second use.
「〜まま」simply says a state hasn't changed, neutrally (靴をはいたまま入ってください = please come in with your shoes on); 「っぱなし」has a feeling of carelessness or 'too much'.
The 「〜続ける」you learned earlier also means 'keep on', but it is neutral.

Watch out

It is not used in polite instructions.
Not with one-off events that finish at once (合格する, 着く) — only with states that can go on.

コンビニのバイトははちじかんたちっぱなしで、あしがパンパンだ。

At my convenience-store job I'm on my feet for eight hours straight, and my legs are killing me.

How it is built (कसरी बन्यो) 立ちます = to stand → drop 「ます」: 立ち → 「っぱなし」 = standing and standing (without sitting even for a moment) → 「で」 → then the bad effect: 足がパンパンだ = my legs are sore and stiff.

いそいでいて、エアコンをつけっぱなしででかけてしまった。

How it is built (कसरी बन्यो) つけます = to switch on → drop 「ます」: つけ → 「っぱなし」 = left on (it should have been switched off) → 「で」 → then: 出かけてしまった = went out (regret).
