Grammar Rule in 30 Seconds

Bulgarian tens (10-90) end in '-десет' (deset), meaning 'ten', making them easy to memorize once you know the base digits.

  • 10 is 'десет' (deset).
  • For 20-90, add the digit prefix to '-десет': 'три' (3) + 'десет' = 'тридесет' (30).
  • Note the spelling change for 60 (шестдесет) and 70 (седемдесет).
Digit + десет = Tens (e.g., 4 + десет = четиридесет)
