Illustrative Context

The canyon is wide here, but further down it’s narrow.

Target Sense

• The basic antonym of narrow (i.e. of gaps, spaces), not the antonym of ‘thin’ (i.e. of objects). That is, the lexeme entered should be the normal adjective to refer to a (horizontal) gap or space between two sides, rather than the (horizontal) breadth of an object or person.
• If a language has a cover term for both of these senses (gap and objects), then as a basic, general term that is indeed appropriate; but if there are different terms, choose the more default one for wide gaps, not things. This is why in English the correct lexeme determination is wide, not broad.
• Avoid terms that primarily have the sense of ‘wide open’ or ‘far’, referring to large distances and emptiness.
• Avoid intensifying terms, such as vast.
