Headword and glosses are all feminine participles in the nominative singular. The headword itself (which must be quoted from somewhere) is the perfect middle/passive participle of the poetic (see LSJ s.v.) verb a)glai/zw. It is glossed by two present participles, one active, one middle/passive.
The entry is taken from the Synagoge (Lexica Segueriana eta248.27), quoted also in Photius, Lexicon eta39 Theodoridis. Compare generally Hesychius eta75: h)glai+sme/non: fwteino/n, lampro/n, 'splendid: [meaning] shining, bright'.
