It's not a tense, exactly, but there's something that really bugs me about English. In Latin and in English there are gerunds, which show continuing action. A gerund has -ing at the end of it: walking, thinking, singing. But in Latin there are also gerundives, which are to gerunds the way gerunds are to regular verbal forms. An English version of a gerund might be walkinging, thinkinging, singinging. It's a way to portray more intense continuing action, and we don't have it.
