Dialectal Variation

British English uses 'barnacle' affectionately for a child ('my little barnacle'), while American English does not. Both use 'barnacle' literally for the marine creature.
Connotations

Frequency
More common in UK English in figurative/affectionate contexts. Marine biology term equally common in both.

Common Mistakes
- Misspelling as 'barnical' or 'barnicle'.
- Using 'barnacle' to refer to any shellfish rather than specifically sessile crustaceans.
