Serve, served. | Dip, dipped (_dipt_). Cry, cried. | Slip, slipped (_slipt_). Betray, betrayed. | Step, stepped (_stept_). Expell, expelled. | Look, looked (_lookt_). Accuse, accused. | Pluck, plucked (_pluckt_). Instruct, instructed. | Toss, tossed (_tost_). Invite, invited. | Push, pushed (_pusht_). Waste, wasted. | Confess, confessed (_confest_). To this class belong the greater part of the weak verbs and all verbs of foreign origin. § 307. II. In the second class, besides the addition of -t or -d, the vowel is _shortened_, _Present._ _Præterite._ Creep Crept. Keep Kept. Sleep Slept. Sweep Swept. Weep Wept. Lose Lost. Mean [57]Meant. Here the final consonant is -t. _Present_ _Præterite_ Flee Fled. Hear [58]Heard. Shoe Shod. Say [59]Said. Here the final consonant is -d. § 308. III. In the second class the vowel of the present tense was _shortened_ in the præterite. In the third class it is _changed_. Tell, told. Will, would. Sell, sold. Shall, should. To this class belong the remarkable præterites of the verbs _seek_, _beseech_, _catch_, _teach_, _bring_, _think_, and _buy_, viz., _sought_, _besought_, _caught_, _taught_, _brought_, _thought_, and _bought_. In all these, the final consonant is either g or k, or else a sound allied to those mutes. When the tendency of these sounds to become h and y, as well as to undergo farther changes, is remembered, the forms in point cease to seem anomalous. In _wrought_, from _work_, there is a transposition. In _laid_ and _said_ the present forms make a show of regularity which they have not. The true original forms should be _legde_ and _sægde_, the infinitives being _lecgan_, _secgan_. In these words the i represents the semivowel y, into which the original g was changed. The Anglo-Saxon forms of the other words are as follows:-- Bycan, bóhte. Sêcan, sóhte. Bringan, bróhte. Þencan, þóhte. Wyrcan, wórhte.
