Key Differences

Underarm is generally used to describe the location beneath the arm, especially in reference to its external surface or when talking about clothing and personal care products. For instance, underarm deodorants are applied to this area to prevent odor. On the other hand, armpit is used more in anatomical or biological contexts, referring to the hollow part beneath the junction of the arm and the body, where sweat glands are concentrated.
When discussing clothing, underarm measurements are crucial for ensuring a proper fit, particularly for sleeves and tops. This term helps tailor and wearers focus on the part of the garment that needs to fit snugly around this area. Whereas, the term armpit is less likely to be used in fashion, except when discussing issues like armpit stains or ventilation in garments to minimize sweat.
In sports and physical activities, underarm techniques or movements are common terms, emphasizing the use of the area beneath the arm for specific actions, such as underarm serves in tennis. Armpit, in contrast, might be mentioned in discussions about body odor issues faced by athletes or the need for breathable fabrics to reduce sweat accumulation in this area.
The underarm area is also significant in beauty and grooming, with discussions often focusing on shaving, waxing, or skin care for this sensitive region. Whereas, armpit health discussions might delve into more medical or hygienic practices, such as the prevention of infections or the importance of regular washing to maintain cleanliness.
Social and cultural attitudes towards the underarm and armpit vary, with the underarm often being a focal point in beauty and grooming industries, promoting products for odor control or skin lightening. On the other hand, the armpit can sometimes carry negative connotations, associated with sweat, odor, or hair, and thus be the subject of stigma or embarrassment in certain contexts.
