El enfermero le tomaba la temperatura al paciente.
So, In the above sentence, I make use of the imperfect form "tomaba" to indicate a continuous or repeated action in the past.
So, The verb "tomar" (to take) is conjugated to match the third person singular (él, ella, usted) in the imperfect tense.
Therefore, This implies that the nurse used to take the patient's temperature regularly or repeatedly in the past. The imperfect tense is often used for actions that were ongoing or habitual in the past.
