KG's Word Puzzles

I like words.

I made some puzzles about the weirder ones in the world.

Here they are.

More to come (probably).

Rules

Most puzzles involving finding a given substring within a word, either because that substring is some other thing or it's just an unusual sequence.

The strings will be organized by difficulty and potentially marked with additional constraints.

"!" indicates the added constraint that the string cannot begin or end the word.
"<>" indicates the added constraint that the string must cross syllables.
