In English one makes gerunds (verbal nouns) and present participles (verbal adjectives) when one adds -ing to a verb. Wrestling may either mean the act of wrestling itself (gerund) or describe someone or something that is wrestling (present participle).

In West Saxon one makes gerunds when one adds either -ing or -ung to a verb, but one makes a present participle when one adds -ende or -iende to the verb.

Gerund
Wrǽstlung is gamen.
Wrestling is a sport.

BUT

Present Participle
Seó wrǽstliende wesle is strang.
The wrestling weasel is strong.

One may wonder when one uses -ing or -ung for gerunds, and when one uses -ende or -iende for present participles. This is truly easy!

When West Saxon verb ends in -ian then one uses -ung for gerunds and -iende for present participles.

wrǽstlian, wrǽstlung, wrǽstliende
to wrestle, wrestling, wrestling

OTHERWISE

One uses -ing for gerunds and -ende for present participles.
