SQL Check if a text contains a word

I have a Text,

'Me and you against the world' // false
'Can i have an email address'  // true
'This is an'  // true

I want to check whether the word an is inside my String.

How do I check if a text contains a specific word in SQL? I can't add a full-text catalog. Otherwies i could

SELECT * FROM TABLE WHERE CONTAINS(Text, 'an')
