collimatev.

/ˈkɒlɪmeɪt/

Etymology: < ‘collīmāre’, an erroneous reading, found in some editions of Cicero, of Latin collīneāre, < col-, com- together + līnea line, līneāre to bring into a straight line. Collīmāre long passed as a genuine word, and was adopted by some astronomers who wrote in Latin (e.g. Kepler Ad Vitellionem Paralipomena, Frankfort 1604, p. 211; Littré) and thence passed into the modern languages. The proper word would be collineate.
