⚠️ 😱The expression "over all" or "overall" with the meaning of "sobre todo" does NOT exist in English. The word you are looking for is "especially".
The adjective 'special' is spelled without an 'e' (special) in all cases.
However, when it comes to the adverb, there are two possible spellings ('especially' /ɪˈspeʃ·əl·i//and 'specially' /ˈspeʃ·ə·li/) and they are used in different contexts and meanings:
Especially: Used to single out one person or thing over all others/ To a great extent; very much. Use "especially" to mean "in particular" or "most of all". (This is, by far, the most frequent use).
Specially: for a special/particular purpose. (Typically used with a participle: this was specially made for me)
