He always keeps his promise.
'Halten' is the base verb for many important verbs with prefixes, such as 'anhalten' (to stop), 'behalten' (to keep / not give away), 'erhalten' (to receive), or 'sich unterhalten' (to talk / converse). The basic meaning of 'halten' often helps you understand these words.
