Medium (Common in UK and Commonwealth English; rare in US English)Informal to neutral, everyday
Definition
Meaning
A brand name that has become generic for a type of ballpoint pen.
Any cheap, disposable ballpoint pen; in some contexts, used humorously to refer to writing instruments in general.
Linguistics
Semantic Notes
Underwent genericization (a proprietary eponym). The sense is nearly always countable ("a biro", "two biros"). While originally a brand, it is rarely capitalized in modern usage outside of trademark contexts.

- False friend with Russian 'перо' (pero), which means 'feather' or 'nib', not a ballpoint pen.
- Direct translation 'шариковая ручка' is the accurate equivalent, not 'biro'.
Common Mistakes
- Capitalizing it as 'Biro' in non-trademark contexts.
- Using it as an uncountable noun (*'write in biro'). It's countable: 'write with a biro'.
- Using it in US English where it will cause confusion.

FAQ
Frequently Asked Questions
No. While it originates from the inventor László Bíró's surname, it is now typically written in lower case ('biro') in general usage, following the pattern of genericized trademarks like 'hoover' or 'escalator'.
Very rarely and informally in British English (e.g., 'I'll biro it down'), but it's non-standard. The standard verb is 'write' or 'jot down'.
A biro (ballpoint) uses a thick, oil-based ink that dries quickly. A rollerball uses a water-based or gel-based liquid ink, which provides a smoother, more vivid line but may smudge more easily.
It's not recommended, as it is likely to cause confusion or require explanation. Use 'pen' or 'ballpoint pen' instead for clear communication.
