Commentary

The affix षच् comes after a बहुव्रीहि समास ending in the word अङ्गुलि when the compound means 'a piece of wood'.
Thus द्व्यंगुलंदारु, त्र्यंगुलंदारु, so also पंचांगुलं ॥ This is the name of a wooden spoon or fork of the figure of a finger by which barley &c are scattered.

Why do we say "in a Bahuvrihi"? Observe द्व्यंगुलयष्टिः = द्वे अंगुली प्रमाणमस्या ॥ It is a Tatpurusha compound formed by 5.4.86, by adding अच् as samasanta affix, the anguli meaning here size and not figure. Why do we say "when meaning a wood" ? Observe पंचांगुलिर्हस्तः ॥
