Underperforming → It is formed from "under-" (meaning below or beneath) and "perform" (from Latin "performare", meaning to carry out or accomplish) and the suffix "-ing" (indicating a continuous action). The word describes the act of performing below the expected level or standard.
Think of 'under-' meaning below and 'perform' meaning to carry out — so underperforming means carrying out tasks below the expected level.
