Dialectal Variation
British vs American Usage
Differences
Pronunciation differs significantly. In BrE, the 'book/guide' sense is often pronounced /ˈpraɪ.mər/, while the 'paint' sense uses /ˈprɪm.ə/. In AmE, the 'book/guide' sense is almost universally pronounced /ˈprɪm.ər/, aligning it with the 'paint' sense.
Connotations
In BrE, the pronunciation /ˈpraɪ.mər/ for the 'book' sense carries a slightly more traditional, old-fashioned connotation (e.g., a child's reading primer). The AmE pronunciation /ˈprɪm.ər/ is standard and modern.
Frequency
The 'book' sense is less frequent in contemporary AmE, often replaced by 'introductory guide' or 'textbook'. The 'paint' and 'biotech' senses are frequent in both varieties.
