x1 (unitless/dimensionless number; li) is the specific gravity (density or concentration ratio) of x2 (substance) with respect to/by standard/per unit of density/concentration of x3 (substance), where density/concentration of each substance is being taken per unit x4 = nildenmi3 at locus x5 = nildenmi4 of density/concentration type x6 = nildenmi5.
x1 [possibly dimensionful number] is the local density/concentration of/in x2 (object) per unit x3 at locus x4, of density type x5; x2 measures x1 units of x5 per unit x3 at locus x4.
x1 is any child of the first child of the first child of ... the first child of x2, where the graph geodesic through the ancestorship-directed family tree from x1 to x2 is of length (x3) + 1 (li; x3 must be a nonnegative integer or positive infinity), and where "first" is according to (partial) ordering rule x4 (default: chronological order of birth per successive generation within the given lineage; other restrictions on legitimacy etc. may be specified here as well).
x1 is any child of the first child of the first child of ... the first child of x2, with intermediate steps x3 (complete ordered list, "ce'o"; should include the relevant parent of x1), where "first" is according to (partial) ordering rule x4 (default: chronological order of birth per successive generation within the given lineage; other restrictions on legitimacy etc. may be specified here as well).
x1 is the vector flux (flow) of quantity/substance (count) x2 through (geometric/imaginary) hypersurface/embedded manifold x3 per unit hyperarea per unit time.
x1 [mass/sequence] plays the Lojban word chaining game (vlalinkei) with ruleset x2 and winner x3 with resulting sentence x4 against world champion x6 for fabulous cash prize x7 and endorsement deal(s) x8 groupies x9 (except they probably go earlier), played at time x10 at location x11 and honorific title x12 breaking record(s) x13 with mindless spectators x14 taking time x15 [amount] containing most frequently used word x16 (zo) and not using perfectly good words x17 (zo) displaying new strategy/trick x18 supervised by x19 with referee x20 and used message transmission system x21 time limit per move x22 shortest move of the game x23 broadcast on TV network(s) x24 with Neilson ratings x25 supplanting previously most watched show x26 winning new fans
x27 who formerly played x28 which is inferior for reasons x29 by standard x30 with banned words x31 with words winning additional points x32 with climax of suspense x33 and best comeback x34
x1 is a region/room/volume of space which is shaped like a washer (or thin or flattened torus/toroid), between inner disk/sphere x2 and outer disk/sphere x3, defined by midplane x4, and containing x5.
x1 is a side of sheet/leaf of paper/page/thin writing surface (card), or is a quantity of text equivalent thereto, of sheet/leaf of 'paper' x2 in document/book/bound mass or sequence of pages x3.
x1 is the x2th-order time-differintegral of the cost/fee/debt or revenue ((possibly: monetary) charge/value) of or at which x3 is sold to/bought by customer x4 from vendor/seller x5, with differintegral starting point x6.
x1 reflects/relates to/pertains to xorlo (Lojbanic) grammatical standards in manner/aspect x2, specific to version x3 (contextless default: the most recent version that has been officially accepted by the Lojban language's governing body (presently, the BPFK))
x1 (text, image, page element) is infra/later-mentioned/subsequently mentioned/later/following/below/toward the bottom of the page/screen (flat and primarily two-dimensional display) relative to x2 (text, image, page element) on page/screen/in work x3 according to cultural convention x4.

x1 (collection, body, set, mass, tuple, n-some, etc.) is x2 (li; default: 1) indivisible/atomic/elementary/basic discrete entities (or particles) of type x3 in composition/content, by standard x4; the count of instances of x3 in x1 is x2 by standard x4.
x1 is Spring time/vernal [warming season] in the northern hemisphere and Autumn/autumnal [cooling season] in the southern hemisphere of year x2 and for celestial body x3.
