This word has a curious history. It is related to the stem -ālm- which means across. The word for bridge was originally jālmīke, derived from -ālm- and the suffix for made things -īk-. However, there is a prefix āl- which is an augmentative prefix, and so jālmīke came to be reanalyzed as ‘large’ + -mīk-, which came to mean bridge.
la jamīki nā sū þō jamāonre mē;
