「Raise, lift」(by hand, perhaps if needed) up to a「tonguing mouth」suggests lifting something to one's tongue and mouth, although it must be noted that a tonguing mouth may as well become the agent that causes other appendages to RISE, ASCEND stiffly and swiftly whether or not contact is achieved with the tongue…particularly when accompanied by「two-handed, head bobbing up and down」or「repeated head bobbing with erection screwing with tonguing mouth, rod in oral orifice」as in this glyph that most likely was applied to PROMOTING THE RANK of a harem concubine or a shaman's service provider after demonstrating exceptional fellatrical skills.
Variant of 升 meaning a CHICKEN HEN ROOST in a CELL or GRID shape of wooden branches used as rails elevated off the ground for birds to roost upon when sleeping. Birds competing every day and night to be raised in a position higher than the other birds:
「By instinct, chickens want to roost ('go to bed') in the highest point available, and be gathered together in a group for protection and warmth while they sleep. Your chickens will be happier animals if you play to their instincts when you are designing their living space. If you were to place multiple roosts inside your coop with some higher than others, they may fight to get the highest ('best') spots: to avoid this, you keep the roost at all the same level. …A chicken roost is a very simple board…or a wooden clothes rod like you would put in a closet, or even a thick tree branch that is about [2-3 inches in diameter].」

A grid or CELL also refers to CONFINEMENT and RESTRICTED MOVEMENT, LOSS OF LIBERTY as when jailed.
Elements and meanings are associated both with chickens and with the lifestyles and relationships of「birds, chicks」as euphemisms for people with no-longer-integrated feet used as sex objects cooped into a harem copulating with only one cock, a rooster that roosts upon the backsides of his female birds. ROOST means to「sleep or rest temporarily」which is not the nest. MEASURED BOX refers to places where hen chickens build a nest and lay, which is not the roost. Both were often made of wood.
A rooster naturally gets around to each hen in the animal harem and services her via copulation on a regular「rotation of emissions」for optimal results and peace within the coop, and the same applies with a gaggle of jealous and very young human females competing constantly for the attention of a single male. The ROOSTS also must be constructed all at the same height, if possible, within a single coop to avoid fighting among the females for the highest roosting perch. MEASURED BOXES for nesting also must be the same relative size for these same reasons (and is why they are called 'measured' so as to assure they are all about the same size and shape).
Some have suggested「sun」「measurable, lifting」as it appears to ASCEND in the sky each morning and then, if the watcher never turns around, would seem to continue ascending all day in an arc across the sky. It is true that a person watching the Sun in this manner may eventually fall over backwards or become very tired of staring upward, and, that the Sun appears to descend in the sky every day just as much as it appears to ascend, so perhaps the top element may more likely be「tonguing mouth」(and, the Sun is unlikely to be「repeatedly raised by two hands」of anyone we know). Nevertheless, some insist the top element is「sun」but be sure to see the Used-In glyphs prior to deciding for yourself.
