Semantic Notes
Primarily a noun, but can be used attributively (e.g., 'suction cup'). The verb form 'to suction' is common in medical/technical contexts.
Dialectal Variation
British vs American Usage
Differences
Minimal. The word is used identically in technical contexts. In everyday use, 'hoover' (UK) vs. 'vacuum' (US) relates to the same suction principle.
Connotations
Neutral in both. In medical contexts, equally standard.
Frequency
Slightly higher frequency in American English due to more prevalent marketing of 'suction-based' consumer products (e.g., suction grab bars).

Frequently Asked Questions
It is standard in technical and medical English (e.g., 'suction the wound'). In everyday life, we use more specific verbs like 'vacuum', 'hoover', or 'suck up'.
A vacuum is a space entirely devoid of matter; suction is the *force* or *process* that results from creating a partial vacuum. In practice, they are often used interchangeably for the resulting pulling effect.
Yes, but carefully. 'The suction of her charismatic personality' is a positive metaphorical use. Literally, it's neutral, describing a physical force.
Yes, etymologically. 'Suction' comes from Latin 'sugere' (to suck). 'Suck' is the everyday verb; 'suction' is the more technical noun for the process/force.
