  • Thoughts and deeds on seeing it:
    (i) Think it's a typo for tachygraph.
    (ii) Web-search. Find it's the valid name for the thing.
    (iii) Think it's malformed Greek and should be tachygraph; web-search 'tachygraph'; find that's a name for something entirely different.
    (iv) Think it's appropriate and reasonable to make the alteration to the more familiar -o- in order to distinguish meanings.
    (v) Look up in OED; be reminded that tákhos "speed" is just as good a Greek word as takhýs "speedy", and that 'tachograph' therefore is well-formed.
    (vi) Enter on Wordie.
    (vii) Wonder if there are single-word verbs for 'OED' and 'Wordie' corresponding to 'google'.
    (viii) Get back to work.
