In this squib I showed some similarities and differences among prenominal phrases in Korean. They all end with a prenominal temporal affixes, called adnominalizers in the literature, which is different from those found in matrix clauses. EHRCs, IHRCs and PA phrases are the same ones in that they contain an empty category coindexed with the relative head. These phrases are different from NPA phrases, gapless RCs and noun complement clauses in that the latter contain no empty category. Among the latter three, NPA phrase and gapless RCs are pure modifiers, whereas noun complement clauses are not.
