What does filching mean?
Filching is the act of stealing something, usually something of little value, in a sly, stealthy, or casual manner. It is the present participle and gerund of the verb filch, and it suggests opportunistic pilfering — pocketing pens from the office, snatching snacks from a shared cupboard, or lifting coins from a counter — rather than burglary or robbery. Because it implies pettiness and sneakiness more than violence or scale, the word carries a tone that hovers between mild disapproval and wry amusement, making it common in informal speech, journalism, and light fiction. Typical phrases include caught filching and filching money or food. The word's precise origin remains uncertain, though it emerged in English around the early seventeenth century and appears to have circulated as underworld slang before entering general use. It remains a vivid, economical alternative to plainer words like stealing whenever the theft involved is small, sly, and faintly comical.

The action or practice of pilfering; an instance of petty theft.
"Constant filching from the communal fridge forced the office to label every lunchbox."
Used chiefly as a gerund; rare as a countable noun.
Filch began life as thieves' slang — and centuries later it's still the perfect word for a theft too small to make the news but too sneaky to ignore.

Etymology of filching
Filch is first attested in English in the early seventeenth century and is widely believed to have originated as thieves' cant, the secret slang of criminals, before passing into everyday use. Its ultimate origin is uncertain, and no secure cognates in other languages have been established, so any deeper ancestry must be described cautiously. From the verb came the agent noun filcher, meaning one who steals petty items.
