Contestant Guidelines

These guidelines are the notes published by the Countdown producers. The first notes outline the general rules that Dictionary Corner use when deciding whether a noun can have a plural.

General noun rules

Nouns in Oxford Dictionaries Premium may be labelled as [MASS NOUN]; in some entries, a countable noun instance may be given, accompanied by a [COUNT NOUN] label followed by an example sentence.

If an entry for a noun has no label, it indicates that the noun is an ordinarily countable noun and so a plural is allowed: for example TABLE - TABLES, BOY - BOYS, LASS - LASSES etc. Plurals of nouns labelled [IN SINGULAR] are also allowed: for example NADIR – NADIRS.

If an entry for a noun has the label [MASS NOUN], it means that the word is not normally or typically used in the plural: for example VIOLENCE or MOHAIR. In these cases, the plurals violences ☓ or mohairs ☓ are not allowed.

However, some entries with the [MASS NOUN] label do also give a [COUNT NOUN] sense, which provides a use of which the plural can be used under a specific context: for example GENOCIDE can be a mass noun or a count noun (‘news of genocides went unreported’), so GENOCIDES is valid.

There are particular types of mass nouns that can take a plural under plausible circumstances, even when a count noun sense isn't explicitly given: for instance, when referring to different types of something such as food. The noun WHEAT, for example, is normally uncountable, but it is possible to talk about a wide selection of WHEATS. Because these types of nouns follow regular rules for forming plurals in particular contexts, the dictionary does not generally indicate that a plural may be allowed. The main types are listed below. Where a noun falls into one of these categories, it means that a plural is usually allowed, though each individual case will be judged on its merits.

Pluralisable mass noun categories

Other areas of adjudication

These notes outline other rules to do with the adjudication of words.

Allowed

Logical inflections e.g. KNIGHTED, SCALDED are fine.

• –AGE

Words in this category denoting an action (BREAKAGE), the product of an action (DOSAGE) or a place of abode (ORPHANAGE) may be pluralized. Many others do not have a logical plural sense (PARENTAGE).

• –ING

The plural of a word ending in –ING will not be allowed unless it is entered in ODO in pluralized form or as a count noun, e.g. ENDINGS is fine but BAKINGS would be disallowed.

• Accented words are allowed, e.g. FIANCÉ.

Disallowed

• –ER agent nouns not in ODO, e.g. CURER is fine but GUESTER is not.
• –ILY words not in ODO, e.g. STUBBILY is fine but MANKILY is not.
• –LESS and –NESS words not in ODO, e.g. EARLESS is fine but BOATLESS is not; REDNESS is fine but BEIGENESS is not.
• UN- and RE- words not in ODO, e.g. UNSAY is fine but UNSCRAPE is not, REWORD is fine but REWATCH is not.
• BE- words not in ODO, e.g. BESTREW is fine but BESCATTER is not.

Conundrums

The conundrum will not end in S to make a plural of a singular word in regular Countdown (though it can do in 8 Out of 10 Cats Does Countdown). Whatever the scramble is, it will never be the answer (so if the conundrum spells out a word when it is first revealed, for example on 8 January 1993, this won’t be the actual answer!)
