All these verbs are irregular, and no others of the 4th conjugation have a circumflex accent on one of the vowels of the stem.

of verb Croître, to distinguish those tenses from the same tenses of verb Croire.

Note that the circumflex accent over u is found in both verbs in the

In the following pages there is a complete list of all the irregular verbs of this first

The model on Servir (to serve) and Craindre (to fear) is quite sufficient to conjugate them all.

Apart from the change of stem in some of the primitive tenses, they are absolutely regular.

As it has been said, Part I., § 57

There are a few verbs of this first class of irregular verbs which keep entire the stem in the primitive tenses.

DERIVATIVE TENSES.

Servir, to serve, to attend, to wait on, to worship, to assist, etc.

All the following verbs are conjugated like Servir, and the irregularity is, as with the same verb Servir, in the Present Indicative:

The irregularity of the following is in the Past Participle,

Départir, Départissant, and Répartir, Répartissant, are compounds of Partir (to divide). These verbs having the prolonged stem iss in the Present Participle, as
