 | | The first is a wff (in fact a conjunction), and the second is a wff (and atomic). | | | Not a wff because '->' must always have a wff on each side (among other things), with parentheses around the whole; '(' is not a wff. | | | By rule 5, this is a wff if A and B are wffs; by rule 1, A and B are both wffs. |

| | Executives were very positive about WFF's atmosphere of commonality and emphasis on networking, but felt WFF had less to offer them on a professional level because the association was catering to the "lowest common denominator" (lower-level executive membership). | | | The groups were comprised solely of Executive Women who had belonged to the WFF for at least two years and attended at least one other national conference. | | | The purpose of the study was to learn these executives' perceptions, opinions, beliefs, attitudes, and behavior regarding the WFF and its programs, and to elicit suggestions for improvement. |

| | Peter Suber, "Three Levels of Truth" |
| | Wff A is logically valid when it is true for every I, not merely satisfiable in every I. A logically valid wff is true for every s in every I. Whether a wff A is logically valid is a function of the language independently of the deductive apparatus. | | | Among atomic wffs, satisfaction is defined differently depending on whether the arguments of the predicate are constants, variables, or functions, and in the last case, whether the arguments of the functions are constants, variables, or functions. | | | Wff A is k-valid iff it is true for every interpretation that has a domain of exactly k members. |

| | With wffs and rules of inference, it's possible to derive wffs; the derivation is a valid argument form, while the derived wff is known as a lemma. | | | Introducing a hypothesis means adding a wff to a derivation not originally present as a premise; discharging the hypothesis means eliminating the wff justifiably--any wffs correctly derived from the hypothesis justify the introduction of the hypothesis after the fact. | | | ; Disjunction Introduction: From any wff φ, we may infer the disjunction of φ with any other wff. |
