Final answer:
The word processing feature that suggests words when a user types the first few letters is known as word completion. It helps increase typing efficiency and productivity.
Step-by-step explanation:
The feature of the word processing program that makes these suggestions as Ryan types the first two letters of words such as today, client, and meeting is word completion. Word completion helps users type more efficiently by predicting the word they intend to type based on the initial letters and frequently used words. This feature saves time and increases productivity by reducing the number of keystrokes needed to complete words that are used often.
