If you mean single as 'unmarried' it would be 独身 (do ku shin) and when used as a modifier you say it like (独身の) (do ku shin - no). E.g I am single : "watashi WA dokushin desu"; a single person : "dokushin no hito".
When you want to say someone is single, 一人 (hi to ri) literally meaning 'alone' can also be used.
If you mean single as 'one, sole' 単独 (tan do ku) can be used.. the 'no' rule with modifier applies to this one as well.
