In English we have the whole set of nine, but in some other languages, (such as German), there's no difference between 'simple', and 'progressive', only the 'perfective', and the 'imperfective'. In Ancient Greek, it *almost* works like German, except that in the past tense, they have all three aspects, for a total of seven conjugations. In Classical Latin, enfuriatingly, the simple past, and present-perfective merged, and so now we have six conjugations, which can't be easily described in such terms.
Simply put, the six latin tenses are as follows:
1. Present - Present Tense and Imperfective aspect. (Equivalent to either 'loves' or 'is loving')
2. Future - Future Tense and Imperfective aspect. (Equivalent to either 'will love', or 'will be loving')
3. Imperfect - Past tense, and Progressive aspect. (Equivalent to 'was loving', but *not* to 'loved')
4. Perfect - Pulls double duty as present-perfective, and past-simple. (Equivalent to either 'loved', or 'has loved')
5. Pluperfect - Past tense, and perfective aspect (Equivalent to 'had loved').
6. Future Perfect - Future Tense, and Perfective Aspect (Equivalent to 'will have loved').
