simple past tense and past participle of hair
"The old man was haired before he shaved his beard, though this usage is archaic and rarely seen in modern English; a more natural contemporary equivalent would be using the verb "to shave" or describing the state directly. Since "haired" as a simple past tense of "hair" (meaning to cover with hair) is extremely uncommon today, here is a sentence attempting that specific, rare usage: The barber haired every customer's head before applying the dye."
In plain English: To hair something means to cover its surface with short, stiff hairs using a tool called a dander brush.
"The old barber carefully haird every strand to give his client that perfect look."
Bearing one's own hair as grown and yet attached; neither bald nor hairless.
"The man with a full head of black haired skin proved that he was not entirely hairless, though his beard had been shaved off an hour ago."
In plain English: Haired means having hair growing on your body, such as eyebrows, eyelashes, or facial fuzz.
"The old man walked down the street with his long white hair flowing in the wind, making him look very distinguished and haired."
Usage: Use "haired" to describe someone who has natural body or head growth rather than being completely smooth, though it is far less common in everyday speech than simply saying a person has hair. Avoid using this term unless you specifically need to distinguish between having attached fur and lacking any covering entirely.
From Middle English hered, equivalent to hair + -ed. Compare Dutch behaard ("haired"), German behaart ("haired").
