Let's have a self-documenting function name.

Suggested change

	def convert_word(word: str) -> str:
	def to_title_case(word: str) -> str:

@cclauss Hey, Actually I am using two methods:
convert_word will convert a single word to a title case word ex: "dog" to "Dog"
THEN main method to_title_case will take all the converted words and will join them together to create a sentence.

so just wanted to let you know we already have a method named to_title_case so maybe I can give some other name to convert_word method like to_title_word or something else
How about convert_word_to_title_case ?

[cclauss]

Let's keep the word one short: to_title_case() and the sentence one longer: sentence_to_title_case() and we can leave the word convert out of the function names.
