Hiberno-English refers to the varieties of English spoken in Ireland that have been influenced by Irish vocabulary, phonology, and grammar. Some key characteristics include the use of Irish-derived words like "banshee", "craic", and "poteen"; rhotic pronunciation and distinct vowel sounds; avoidance of "yes" and "no" in answers; and grammatical constructions like "does be/do be" to indicate continuous present tense. Characteristic expressions in Hiberno-English come from Irish phrases and include terms like "arra", "come here to me now", and "to give out to somebody".
