Modals in the Past! Můžu to udělat zítra. I can do that tomorrow. J Mohla jsem to udělat vcera. (I could do that yesterday.) L Problem!!!! Could is also used for our conditional, so we don’t know if you mean “Mohla jsem” or “Mohla bych.” L Solution!!!! J Instead of (or in addition to) putting the modal verb into the past, put the INFINITIVE into the past: Do = present infinitive Have done = past infinitive (have + 3. tvar) I could HAVE DONE that yesterday.
