In Finnish, the instructive case is used to indicate means, manner, instrument, location, or time.
It is almost exclusively used in fixed expressions, such as in omin silmin 'with one's own eyes'.
[2] In modern Finnish, many of its instrumental uses are being superseded by the adessive case, as in minä matkustin junalla 'I travelled by train'.
[citation needed] The instructive case is only marginally present in Estonian in lexicalized expressions.
[3] In Turkish, the suffix -le is used for this purpose; for example, Trenle geldim 'I came via train'.
