Some substantives are what the grammarians call aggregate plurals, "which are not used in the plural without the addition of diminutive terminations, for example adar, birds, aderyn, a bird; gwenyn, bees, gwenynen, a single bee." There are different kinds of adjectives; some have a plural, some have none; some have a feminine form, others have not; the most common plural termination is ion.
