is a cliché and to be avoided. For “employment on a part-time basis” say “part-time employment”. Other usages are similarly redundant (“on a regular basis” — “regularly”; “on a daily basis” — “daily”; “on a voluntary basis” — “voluntarily”, “willingly”, or “without pay”, depending on context; and so on)
Basle (Switzerland), not Basel or Bâle. But note, FC Basel, the football team, and Art Basel, the art fair
Basque country, the
bated/baited note the difference: bated breath; baited hook; bait as a verb is to persecute, tease or torment (as in bear baiting); bate is the verb to use of a tethered hawk beating its wings and trying to jump from its perch, should you have occasion to write about such a thing
battalion never batallion. Say the 1st Battalion, the 7th Battalion etc (not First, Seventh)
battle try to avoid using as a transitive verb as in “The students battled the police …”; use “fought” or “battled against” instead; be wary of using at all (along with similar language) in relation to illness (battle against cancer etc)
battle cry
battleship a heavily armoured warship of the largest type, with many large-calibre guns. Beware. Battleship is not synonymous with warship: eg cruisers and destroyers are warships but they are not battleships. Historically, a battleship (line-of-battle ship) was any warship of sufficient size and armament to take her place in the line of battle; in other words, a ship of the line
BBC no need to spell out as British Broadcasting Corporation, although “the corporation” is a useful alternative in text. Avoid “the Beeb” except, on rare occasions, in columns or commentaries . The BBC is an organisation fond of capitals. Most are unnecessary. BBC job titles, like any others, are lower case: controller, chairman, director-general, governor. So are BBC television and BBC radio and the BBC charter. The BBC Trust may be capped when there is a risk of ambiguity, but is generally lower case. Caps for the historic radio stations: the Light Programme, the Home Service and the Third Programme
BC See AD
be-all and end-all note hyphens

bedizened archaic but lovely word meaning dressed or decorated gaudily or tastelessly
Bedouin prefer to Beduin for the nomadic peoples of Middle Eastern and north African deserts
beg the question refers in logic to an informal fallacy whereby an argument assumes its own conclusion: eg “this usage is unattractive because it is ugly”; that sense seems worth preserving. More commonly used as just another (less good) way of saying “raise (or ask) the question”; some readers are (logically) annoyed by this
beleaguered a cliché, especially in a political context, so best avoided

betting odds use a hyphen (16–1, 6–4 etc), not a slash (16/1). For odds-on, smaller figure comes first (1–2, 4–11 and so on). The higher the odds, the less likely something is; if the chances of something happening are raised, the odds are lowered. Not everyone understands odds as well as they think they do. If in doubt, consult the racing desk
bi- take care with this difficult prefix. Its correct use is in Latin compounds, where it has the force of two, not half, such as bicentenary/bicentennial (a two-hundredth anniversary), or biennial (recurring every two years). Biannual means twice a year; to avoid confusion, write out twice a year
biased

billion one thousand million, not a million million. Write £5 billion, £15 billion (£5bn, £15bn in headlines), three billion, 15 billion etc
bin Laden, Osama note lower case “bin”, except where it is the first word of a headline or sentence. Avoid the “Mr” designation, as with Saddam Hussein etc. The organisation founded by bin Laden is al-Qaeda (not al-Qaida). Bin Laden was killed in his compound in Abbottabad, Pakistan, in the early hours of Monday, May 2, 2011 (time differences mean it was still May 1 in Washington and London)
bin liner
biological terms with Latin terms, cap letter for first (genus) word, then lower case for the second (species); and italicise for all but the most common, eg Turdus merula,
