How do you want me to explain it?

How about in writing?

Look, Fae magic and Mortal Sorcery are two different things. With Mortals, most of the magic comes from without. With Fae, most of it comes from within. Fae are made of magic.

After that clear distinction, the specifics depend on control, style, training, power, i.e. lots of factors. Anansi spins his spells. Puck rhymes his. Oberon is so powerful he just has to speak his will. But rhyming helps, so he does that too sometimes. Most Fae rhyme, but there are plenty of exceptions.

Mortals need something to gather and focus energy. A place, a talisman, a spell.

I'm not exactly sure if that answers your question. If you need more specifics, post again.
