Overview
The verbs are gróa ("to heal, to grow"), núa ("to rub, to wipe"), róa ("to row") and snúa ("to turn"). Another peculiar thing about the ri-verbs is that they are written with an e in the second principal part (first person singular past indicative mood), even though they are pronounced as being spelled with an é; according to the Icelandic Ministry of Education.
The principal parts of the ri-verbs are as following:
| First principal part | Second principal part | Third principal part |
|---|---|---|
| Infinitive | First person singular past tense indicative mood | Past participle |
| Að snúa ("to turn") | Ég sneri ("I turned") | Ég hef snúið ("I have turned") |
| Að gróa ("to heal") | Ég greri ("I healed") | Ég hef gróið ("I have healed") |
| Að núa ("to rub") | Ég neri ("I rubbed") | Ég hef núið ("I have rubbed") |
| Að róa ("to row") | Ég reri ("I rowed") | Ég hef róið ("I have rowed") |
The Dictionary of the University of Iceland and the Icelandic dictionary for schools and offices still mention "snéri" as another orthography of "sneri".
