Fasten down Meaning in English
expression
Definition
To make something secure or tight, usually by tying, locking, or attaching it firmly so it won’t move or blow away.
Usage & Nuances
Commonly used in practical situations—like storms or transport—when items must not move. Often appears with nouns like 'windows', 'lids', or 'objects'. More informal than 'secure', but standard in spoken/written English. Not the same as 'fasten' (general) or 'tie down' (often with ropes/straps).
