Definition: useless, serving no purpose, superfluous; the word is usually used in the sense of useless or futile in connection with a rule or its part, which serves no purpose, its purpose or object being served otherwise; such words or rules have never been condemned as futile by commentators, but an attempt is made invariably by them to deduce something from the futile wording and show its necessity; cf. व्यर्थे सज्ज्ञापयति a remark which is often found in the commentary literature; cf. अन्यथा अन्तरङ्गत्वाद्दीर्घे कृत एव प्रत्ययप्राप्त्या तद्यर्थता स्पष्टैव । Par. Sek. Pari. 56; (2) possessed of various senses such as the words अक्षा: माषा: etc.: cf. व्यर्थेषु च मुक्तसंशयम् । M.Bh.on P.I.2.64 Vart. 52. The word व्यर्थ possibly stands for विविधार्थ in such cases. It appears that the word व्यर्थ in the sense of futile was rarely used by ancient grammarians; the word अनर्थक appears to have been used in its place. See Mahabhasya in which the word व्यर्थ does not occur in this sense while the word अनर्थक occurs at several places.
