The standard of comparison is normally introduced by ku. It is useful to note that this is only one of several different uses of ku, which is also a comitative preposition ('with'), a NP conjunction ('and'), and a complementizer ('that') which introduces finite subordinate clauses and relative clauses.
The standard can also be introduced by manera 'as if' (Maurer 1988: 36). Birmingham further points out that an alternative to menos is the expression using no asina [Adjective] manera [standard] (1970:47)
