逻 is a bound form (b.f.) — it never appears alone but only within compound words. The two most common compounds are 巡逻 (xúnluó, 'to patrol, go on patrol') and 逻辑 (luóji, 'logic'), the latter a Meiji-era Japanese loanword from Greek λόγος (logos). As a bound form, 逻 does not carry a standalone meaning; its sense is determined entirely by the compound it appears in.
