Subsequent is an adjective of two genders that classifies some thing that comes after, or what follows. It is synonymous with immediate, further and Following.
An event qualified as subsequent happens after something else, and can refer to time or space. Ex: The catastrophic earthquake and subsequent lack of water and light caused many deaths.
Many people have doubts about the spelling of this word, between subsequent and subsequent. The umlaut was used in words with syllables like que, qui, gue and gui, when the letter "u" was pronounced.
The Spelling Agreement of 1990 provides for a new spelling of word, no tremor, that is, subsequent. The explanatory norm of the orthographic agreement indicates that the "complete suppression of the umlaut" must be carried out, with the exception of words derived from foreign proper names, such as Müller.
Within the scope of technical courses, some institutions have subsequent and concurrent courses for students who intend to obtain professional education. Concomitant means coexisting, which happens at the same time, and that is why the concomitant technical course allows the student to enter the course while attending high school. On the other hand, the subsequent technical course is aimed at students who have already completed high school.
