n.
A low fleshy fern (Botrychium Lunaria) with lunate segments of the leaf or frond.
n.
A mock moon; an image of the moon which sometimes appears at the point of intersection of two lunar halos. Cf. Parhelion.
n.
The herb moonwort or "honesty".
a.
Satin flower; the name of two cruciferous herbs having large flat pods, the round shining partitions of which are more beautiful than the blossom; -- called also lunary and moonwort. Lunaria biennis is common honesty; L. rediva is perennial honesty.
n.
A lunar distance.
n.
The time of the new moon; the beginning of the month in the lunar calendar.
n.
The time of the apparent revolution of the sun trough the ecliptic; the period occupied by the earth in making its revolution around the sun, called the astronomical year; also, a period more or less nearly agreeing with this, adopted by various nations as a measure of time, and called the civil year; as, the common lunar year of 354 days, still in use among the Mohammedans; the year of 360 days, etc. In common usage, the year consists of 365 days, and every fourth year (called bissextile, or leap year) of 366 days, a day being added to February on that year, on account of the excess above 365 days (see Bissextile).
a.
Measured by the revolutions of the moon; as, a lunar month.
n.
The middle bone of the proximal series of the carpus; -- called also semilunar, and intermedium.
a.
Influenced by the moon, as in growth, character, or properties; as, lunar herbs.
a.
Resembling the moon; orbed.
a.
Of or pertaining to the moon; as, lunar observations.
n.
The bone or cartilage between the radiale and ulnare in the carpus, and between the tibiale and fibulare in the tarsus. It corresponds to the lunar in the carpus, and to a part of the astragalus in the tarsus of man and most mammals.
a.
Lunar.
a.
Of or pertaining to the scaphoid and lunar bones of the carpus.
prep.
The alternate rising and falling of the waters of the ocean, and of bays, rivers, etc., connected therewith. The tide ebbs and flows twice in each lunar day, or the space of a little more than twenty-four hours. It is occasioned by the attraction of the sun and moon (the influence of the latter being three times that of the former), acting unequally on the waters in different parts of the earth, thus disturbing their equilibrium. A high tide upon one side of the earth is accompanied by a high tide upon the opposite side. Hence, when the sun and moon are in conjunction or opposition, as at new moon and full moon, their action is such as to produce a greater than the usual tide, called the spring tide, as represented in the cut. When the moon is in the first or third quarter, the sun's attraction in part counteracts the effect of the moon's attraction, thus producing under the moon a smaller tide than usual, called the neap tide.
n.
The addition of a day to the lunar calendar.
a.
Pertaining to conjunction, especially to the period between two successive conjunctions; extending from one conjunction, as of the moon or a planet with the sun, to the next; as, a synodical month (see Lunar month, under Month); the synodical revolution of the moon or a planet.
n.
Any fern of the genus Botrychium, esp. B. Lunaria; -- so named from the crescent-shaped segments of its frond.
n.
An inhabitant of the moon.
