This is a good example because it also shows the u-umlaut which would have taken place even without the past tense ending. It should be mentioned however, that some weak verbs will undergo another umlaut known as the i-umlaut. This will cause the vowel in the stem to change like the u-umlaut but this vowel change does not make it a strong verb. To recognize weak verbs, it is crucial that you recognize their weak endings.
The u-umlaut changes any a to ö when followed by a u. The i-umlaut affects several vowels in several ways. If an e is followed by an i then the resulting vowel is a. Example: segja in the past becomes sagði.
If the letter yi, the resulting vowel change is u. Example: spyrja in the past tense becomes spurði. If the diphthong au is followed by an i then the resulting diphthong is ey. Example: kaupa in the past becomes keypti.
