Air holes are small openings or perforations through which air can pass. There are several synonyms that can be used to describe these openings. Breathing holes, vents, air vents, air ducts, and air passages are all common terms used to refer to air holes. These synonyms can be used in different contexts such as in construction, where air holes are necessary for proper ventilation, or in sportswear where breathable fabrics are used to allow air to circulate. Additionally, air holes can also refer to the gaps or spaces in frozen lakes or rivers where the ice is not as thick, and terms such as thin ice, break up areas, or weak spots can be used as synonyms for air holes in this sense.
