Questions & Answers about Frun lär ha en hemlig älskare.
Doesn't lär normally mean 'learns' or 'teaches'?
It does! As a regular main verb, lär means 'teaches' and lär sig means 'learns'. However, when used as an auxiliary (helping) verb followed by an infinitive like ha, it completely changes meaning. It becomes a modal verb expressing either hearsay ('is said to') or high probability ('is likely to'). Here, it expresses hearsay.
How do we know lär means 'is said to' here, rather than 'probably'?
It relies entirely on context, as lär can mean both. However, gossip about a secret lover (en hemlig älskare) strongly implies hearsay—rumors that people are actively spreading. If the context were predicting an outcome, like hon lär vinna (she will probably win), it would express probability.
Why is it just ha and not att ha after lär?
Because lär acts as a modal verb here (just like kan, vill, or måste). Modal verbs are always followed directly by the bare infinitive of the next verb, without the word att (to).
Could I use ska instead of lär to express hearsay here?
