- impractical
- impracticable, impracticalThese two words have related meanings to do with the impossibility of doing something, and correspond to the positive forms practicable, practical. Impractical is a relatively recent (19c) word and means the same as unpractical, i.e. ‘not practical or realistic’; it can also be used of a person, with the meaning ‘lacking the ability to do practical things’, and usually has a general application. Impracticable means ‘not able to be carried out, not feasible’, and is more usually applied to particular cases. In practice, however, the two words are close enough in meaning to run the frequent risk of getting in each other's way:
• As his arms were full of books it would have been impracticable for him to wave —J. I. M. Stewart, 1974
• I have always been ridiculously impractical…I cannot repair a fuse —F. Howerd, 1974
• Her plans were so impractical that someone like me was necessary to point this out —Anita Brookner, 1987
• It would be impracticable to provide full-time security in cemeteries —Birmingham Post, 2003
• If she lost her licence it would have a catastrophic effect.…It would be totally impractical for her to use public transport —Essex Chronicle, 2007.
