This is a continuation of last week's lesson on verb tense. Today we're going to delve a little deeper —make that way deeper —i nto the issue. But, basically, the concept is the same. Verb tense is relative. Pay attention to the tense you're writing and stay true to that according to when the various actions happened in relation to each other. Do not shift from one tense to another if the time frame for each action or state of being is the same . Last week I mentioned basic conjugation, including past participle . For the infinitive 'to play,' that would be has/had played . I've noticed writers seem to make more errors when using past participle — both with regular and irregular verbs . One situation that often leads to an error is combining a contraction with one of these verbs. Let me show you what I mean.
