The following article undertakes another analysis of affixation in Polish Sign Language (PJM). This time the question concerns affixes carrying temporal significance. In a previous issue of this journal, negative affixation in PJM was discussed. As it turns out, in addition to these negative morphemes, PJM also possesses suffixes that relate to time: year, day, hour, minute and second. It has been observed that these affixes have undergone partial or complete grammaticalization. As discussed in this paper, there are some restrictions on the use of temporal suffixes, which are caused by numeral incorporation. In addition to these affixes, there are also two morphemes in PJM, which do not represent a time measure. One of these signifies the completion of an educational stage and the other refers to the future performance of an action.
