I have seen lists of stem-changing verbs, and a large group of those are verbs with ei or ie in the stem.
Is the presence of those two-letter combinations an automatic indicator that the verb is stem-changing?
I came across meinen, so there´s at least one. Is that the exception, or the rule?
Many verbs with /ie/ or /ei/ are strong verbs, mostly belonging to either class I (infinitive with /ei/, e.g. bleiben) or class II (infinitive with /ie/, e.g. fliegen), but not all verbs with /ie/ or /ei/ are strong.
Examples for weak verbs with /ie/: siegen, quieken.
Example for a weak verb with /ei/: zeigen.
