x_{1} is the result of applying logical connective/conjunction x_{2} to the terms of the ordered list x_{3} in the order given, in system x_{4}

x_{1} is not the truth value of the result, but the result itself. x_{2} is filled by a function or a la'e-prefixed quote of a connective (CON; JA*, JOI*). In Lojban, the terms of the ordered list in x_{3} need not syntactically match the connective used; for example, bridi tails can be used even when ja (as opposed to gi'e/gije) fills x_{2}. The connective filling x_{2}, if n-ary, will operate on the first n terms of the ordered list filling x_{3}, then it will successively operate on the result and the next n-1 terms (after the previously used ones) of the ordered list in x_{3} where the the result and terms fill its argument slots in the order presented. Thus, the ordered list which fills
x_{3} must be of an appropriate length; the recommendation is that exactly n terms are included; only explicitly mentioned terms are included. The terms of the ordered list in x_{3} and their results must be comparable; they can be sumti, bridi (la'e-prefixed quoted predicates; not its truth value), Booleans, sets, etc. This word can be used to express the notion of "logical conjunction", "logical disjunction", "set-theoretic union", "set-theoretic complement", etc. (the result, not the process, in each case); the terms of the list in x_{3} would be the conjunct(and)s (or their logical parents), etc. See: fancufacki, terjoma.
