Questions & Answers about Sie hat beim Gespräch geweint.
I thought bei meant at or with. Why does it translate to during here?
You are right that bei often means at or with for locations and people. However, when used with an event or an activity like Gespräch, it acts as a temporal preposition meaning during or at the time of.
Why is it beim instead of just bei?
Beim is the standard contraction of bei and dem. The preposition bei always requires the dative case. Because conversation is a neuter noun (das Gespräch), its dative article is dem.
Why are hat and geweint separated by the rest of the sentence?
This is the standard German word order for the spoken past tense. The helping verb hat takes the second position in the sentence, while the past participle geweint is pushed all the way to the end.
How can I tell if weinen (to cry) is a regular or irregular verb just by looking at geweint?
You can tell it is a regular or weak verb because its past participle geweint ends in -t. Irregular verbs usually end in -en in their past participle form, like gesprochen or gesehen.
