None of the lossless entropy encoding methods so far have addressed compression of small strings of arbitrary lengths. Although it appears inconsequent, space occupied by several independent small strings become significant in memory constrained environments. It is also significant when attempting efficient storage of such small strings in a database where while block compression is most efficient, retrieval efficiency could be improved if the strings are individually compressed. This paper formulates a hybrid encoding method with which small strings could be compressed using context aware static codes resulting in surprisingly good ratios and also be used in constrained environments like Arduino. We also go on to prove that this technique can guarantee compression for any English language sentence of minimum 3 words.
