Find and return a word in a sentence in SQL

I have a column in my SQLite database which contains a long string. For example:

This is almost a long sentence in the column I have mentioned!

I want to pass some letters of a word and get the entire word, not the sentence itself! For example, I want to enter sen and get the word sentence.

I'm looking for a way to execute an SQL query to do so, is there any solution?
