The Botevgrad dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Botevgrad and Etropole in northwestern Bulgaria. It is located on the yat boundary and is closely related to the Eastern Bulgarian Pirdop dialect.

Phonological and morphological characteristics

• Vowel a for Old Church Slavonic ѫ (yus), ь and ъ: маж vs. formal Bulgarian мъж (man), сан vs. formal Bulgarian сън (sleep). However, Old Church Slavonic ъ has resulted in o in the prepositions and prefixes във and въз: вов водата vs. formal Bulgarian във водата (in the water). The schwa is usually pronounced only in Turkish words, e.g. бакър (copper)
• Vocalic r and l for Old Church Slavonic ръ/рь and лъ/ль instead of the combinations ръ/ър (rə~ər) and лъ/ъл (lə~əl) in Standard Bulgarian - дрво, слза instead of дърво, сълза (tree, tear).
• Lack of iotation between two vowels: копаа (also копам) vs. formal Bulgarian копая (to dig)
• The masculine definite article is -a, as in the Pirdop dialect: кра'ка (the leg)
• Verb ending -a instead of formal Bulgarian -ъ in verbs of the first and second conjugation: чет'а vs. formal Bulgarian чет'ъ (I read)
• Future tense particle is ща for 1st person and ще for all other persons (ще in all cases in Standard Bulgarian)
• Personal pronouns for 3rd person той, тʲа, то, тиа (той, тя, то, те in Standard Bulgarian)
