使用する際の注意点

• Only certain verbs can take un- to form a new word with the opposite meaning. In particular, verbs that describe an irreversible action produce words often considered nonsense, e.g. unkill, unspend, unlose, unring. These words may nevertheless be in occasional use for humorous, ironic or rhetorical effect.
• Although this prefix and Etymology 1 are homonymous and semantically similar (both relating to negation), they generally do not collide as they apply to different parts of speech. Ambiguity can however be caused when used with other derivational affixes; for instance unlockable can be parsed as either unlock -able (“[a lock] that is able to be unlocked”) or un- lockable (“not capable of being locked at all”).
  • It is possible for a word to contain both prefixes, e.g. unundoable, but this is generally avoided due to being clumsy or unclear.
