subduct

verb

Etymology: From Latin subductus.

1. To push under or below.

   “The upper tectonic plate had been subducting the lower one for millions of years by the time the eruption happened.”

2. To move downwards underneath something.

   “This tectonic plate had been subducting for millions of years by the time the eruption happened.”

   “For example, if two trenches remained fixed relative to the local parts of the mesosphere into which they were subducting and if these two parts of the mesosphere were moving relative to each other, then the positions of the two trenches would move in the fixed reference frame. However since on Planet B the rate of deformation of the mesosphere is much slower than the rate of plate motion, we would still be able to draw the useful conclusion that the rate at which trenches and their subducting slabs move laterally relative to the mantle is very slow.”

3. To remove; to deduct; to take away; to disregard.

   “He wished to subduct the caveat that he had entered earlier.”

   “Should it be desired to subduct the caveat the party entering it or his clerk, on producing the receipt, writes in the margin of the caveat "I subduct this caveat," and signs his name. If deceased had a residence within the limits of a district registry notice of the caveat is sent to such registry. Fee for entering caveat at principal registry, 1s. 〃 notice of entry to district registry, 1s. 6d. Same fees are charged for subducting.”
