TYPICAL ERROR We hanged the shield in the foyer.
CORRECTION We hung the shield in the foyer.
EXPLANATION When we change from one tense to another in English, the change is usually indicated by simple changes to verb endings. Such changes to the verb are called inflections (which literally means bendings, as in flexible).
The inflections of some verbs can be confusing because they are slightly unusual: for example, the verb to hang (a picture) does not change from hang to hanged, as one might expect, but to hung. (The word hanged refers to execution.)
