Ihre Antwort war kurz und unmissverständlich.
Her answer was short and unambiguous.

unmissverständlich vs klar
clear
'klar' and 'unmissverständlich' can both mean that you understand something well and do not have to doubt it. 'klar' is more general and fits many situations: 'eine klare Erklärung' (a clear explanation), 'eine klare Regel' (a clear rule), or 'ein klarer Plan' (a clear plan). 'unmissverständlich' is stronger. It emphasizes that a misunderstanding is practically impossible. It is often used for announcements, warnings, rules, or opinions that are formulated very clearly. A memory tip: 'klar' means easy to understand; 'unmissverständlich' means so clear that no one should misunderstand it.
