It is composed of two parts: voj – "troops"/"war(rior)" and těch – "consolator"/"rejoicing man".
The name Vojtěch is since the Early Middle Ages also perceived as the equivalent of Germanic name Adalbert ("noble bright"), due to the saint Adalbert of Prague (Czech: svatý Vojtěch; Polish: święty Wojciech), however, the two names have no linguistic relationship with each other.
The caron modifies the pronunciation of the letter 't' immediately preceding the ě.
The second is a digraph at the end of the name: the last two letters 'ch' in fact form a single phoneme (pronounced as a voiceless velar fricative [x]).
A common shorter version of the name is Vojta, pronounced [ˈvojta].
