waning
When the moon appears to be shrinking, it is said to be waning. This phase occurs as the amount of illuminated surface visible from Earth is decreasing. It gradually transitions from a full moon to a new moon.
A crescent moon is growing when it transitions from a new moon to a first quarter moon, and shrinking when it transitions from a last quarter moon to a new moon. The growth or shrinkage of the crescent moon is a result of the changing angles between the sun, moon, and Earth during the moon's orbit.
Waning.
A WANING Moon. An increasing Moon is called a waxing Moon. NB From New Moon to first quarter it is a WAXING CRESCENT Moon From 1sr Quarter to Full Moon it is a WAXING GIBBOUS Moon From Full Moon to Last Quarter it is a WANING GIBBOUS Moon From Last Quarter to next New Moon it is a WANING CRESCENT Moon.
It is said to be waning, and waxing when the moon's light is increasing.
we don't know yet but the moon is shrinking
The "more than 50%" moon is called the gibbous moon. When it is "growing" (appearing to get larger), it is a Waxing Gibbous; when "shrinking," it's the Waning Gibbous.

A "shrinking moon" refers to the phenomenon where the moon appears to be decreasing in size, usually during its waning phase. This is a natural occurrence as the illuminated portion of the moon visible from Earth decreases over the course of the lunar cycle.
The apparent size of the moon's illuminated portion is constantly shrinking during the two weeks after Full Moon, leading up to New Moon ... not only daily, but continuously, even hour by hour. This portion of the moon's cycle is called the "waning phases".
The moon is in its waning (shrinking) gibbous phase for roughly the week after the Full Moon.
Nothing whatsoever. The Moon is apparently shrinking a tiny bit, because the core of the Moon has been cooling and shrinking - but the net effect, from 250,000 miles away, is precisely zero. As long as the mass of the Moon stays the same (and it is) and the ORBIT of the Moon remains the same (and it is!) then the gravitational force on the tides is entirely unchanged.
