Irregular and t-Suffix Weak Verbs

The verb gaggan 'to go' was originally a reduplicated verb of the strong class VII. It nevertheless once shows a weak preterite gaggida in WG; generally the suppletive forms iddja, iddjes, and so on, supply the past tense of gaggan. Some weak verbs Proto-Germanic lacked the medial -i- between the root and dental suffix. This phonetic environment led to -t- as the reflex of the dental suffix in the past forms. The verb káupatjan 'to buffet' falls into this category, though the past participle shows -i-. The following is a list of the verbs showing these peculiar features.
