What does retentive mean?
Retentive describes a person, mind, or ability that is good at remembering and preserving information. The word is especially associated with a strong, reliable memory and often appears in expressions such as "retentive memory," "retentive ability," and "retentive powers." It can suggest not merely the capacity to learn something, but the ability to keep it available over time. In a more technical or formal sense, retentive can describe something designed to retain or hold another material, such as moisture, heat, or a charge. The usual meaning is favorable and emphasizes careful observation and recall, although the word can sound slightly formal in everyday conversation. For general description of a person, "having a good memory" is often more natural and immediately understandable.

This is the dominant modern meaning.

Where does retentive come from?
Retentive comes through French from Latin retainere, meaning "to hold back" or "to keep," and ultimately from the Latin roots re-, meaning "back" or "again," and tenere, meaning "to hold." The same root produced the English words retain and retention. Its early sense developed from keeping or holding something and later extended to the ability to remember information.
