The feature vf-m applies to all verbs. A set of defective verbs does not realise all vf-m values:
Examples:
- Impersonal verbs like neiger /, pleuvoir /, etc.,
do not have verbforms with the vf-m value imperative.
- Only the past participle form of reclure / is used.
- The verb renaître / has no past participle. Consequently, this verb has no compound verbforms.
