One of the most interesting topic within the modal verbs
are the verbs shall and must. Shall and must seem to
be quite simple and easy as long as you do not think
too much about it. There is the issue of being polite
or rude and then there is the common use of shall as
a future form etc. The point here is it's better to
understand the differences before we can explain how
they are used in Spanish. Therefore, we start to think
a little bit about the English use of shall and must.
What does it actually mean and when these modal
verbs are used?
In general, one could say that the use is in quite a
similar way, but we'll go all the way step by step.
