These pairs of verbs cause confusion because both verbs in each pair have similar-sounding forms and related meanings. In each pair, one of the verbs is transitive, meaning that it is followed by a direct object (I laid the cloth on the table). The other is intransitive, meaning that it does not have an object (He lay on the floor when his back ached). The best way to avoid confusing these verbs is to memorize their forms and meanings.
