Quite a few words will appear on a list of four letter words that start with the letter S. S is an easy letter to start off a word with, because it lends itself to blending with so many other sounds. For example, if we take the letter Q, we almost always need U to come after it. Two other difficult letters are X and Z, and we really do not see a plethora of words starting with either of these letters.
The following list contains a number of words which fall into this category.
When using items from the list of four letter words that start with the letter S, there really are only two “rules” so to speak. Of course, aside from those, you must make sure that you are using the word correctly. Not many of the words on the list are exceedingly difficult to understand, so that is probably not a big problem for many individuals.
The other two items are as follows. If you are writing a poem that focuses on assonance, using a few of these words in a row would be a rhetorically splendid idea! Not only will doing so fulfill the requirements of an assonance poem, but also give the reading a steady beat, since all the words are of the same length.
However, if you are not writing some sort of creative assignment, particularly one calling for all words of the same starting sound and length, be careful with using too many of these words in a row. In a research paper for instance, writing 10 of these words in a row is going to sound silly. It is going to sound as though you were trying too hard to be an advanced writer. The end product of such an action will make you look like an amateur writer, not one superior in his or her writing skills.
