Žáček (pronounced: zha-chek) is a Czech surname.
The etymology is "little student" from a diminutive of wikt:Žák. Polish (Żak), Czech (Žák), and Slovak (Žiak): nickname for a youthful or studious person, from Polish żak ‘student’, ‘schoolboy’. The original meaning of this word was ‘novice’, ‘candidate for the priesthood’, and so in some cases it is perhaps a nickname for someone who had been destined for holy orders.
