What does aspirated mean?
Aspirated describes a consonant sound produced together with an audible release of breath. In phonetics, it most often characterizes voiceless stops such as p, t, and k when they begin a stressed syllable in English: say 'pin' with your palm near your lips and you will feel a distinct puff of air, whereas the same letter in 'spin' lacks that puff. Languages differ markedly in how they treat this feature — some distinguish words purely by whether a consonant is aspirated or not — which makes the term essential to linguistic analysis and language teaching. The word also appears in medicine, where 'aspirated' can mean withdrawn from the body by suction, as in fluid removed during an aspiration procedure. Though technical rather than conversational, it offers a vivid reminder that speech involves physical breath as much as vocal sound.
(Of a consonant sound) Pronounced with an audible puff or burst of air accompanying its release.
"English speakers typically produce the 'k' in 'kite' as an aspirated consonant."
Used chiefly in phonetics and language-teaching contexts.
Past form of 'aspirate': pronounced (a sound) with an audible release of breath, or removed (fluid or foreign matter) by suction.
"The surgeon aspirated the excess fluid from the patient's knee joint."
The medical sense applies to the act of withdrawing material using a syringe or similar device.
Say 'pin' holding a tissue in front of your mouth — it flutters. That flutter is aspiration, and it's why 'pin' and 'spin' don't sound quite alike even though they share letters.

Etymology of aspirated
Aspirated derives ultimately from the Latin verb 'aspirare', meaning 'to breathe toward or upon', formed from 'ad-' ('toward') and 'spirare' ('to breathe'). The related noun and verb 'aspirate' entered English around the early 17th century, initially carrying meanings connected to breathing before settling into its modern phonetic sense. The Latin root 'spirare' has proven remarkably productive, yielding cognates such as 'inspire', 'respire', 'perspire', and 'spirit'.
