Question

Special delicates lingerie detergent is unnecessary.

Does this sentence need commas or is this sentence punctuated correctly?

Answer 1

It doesn't make any sense, regardless of punctuation.

Oh -- unless you mean special, delicates, and lingerie are all adjectives modifying detergent. If so, it's an awkward and confusing sentence.

Answer 2

The sentence would be better if you wrote this:

Laundry detergent for especially delicate lingerie is unnecessary.

Answer 3

Choose the correctly punctuated sentence.

When she told him "Those socks are interesting" she meant the socks looked ridiculous.
When she told him, "Those socks are interesting," she meant the "socks looked ridiculous."
