Analysis. paṭi + akkha: paṭi 'back, against' + akkha 'eye', hence 'against the eye', i.e. facing directly, manifest to perception. The gerund paccakkhāya 'renouncing' extends this to 'speaking against' or 'disavowing'.
Etymology. paṭi (prefix, 'back, against') + akkha (eye, from √akṣ 'see'). Akkha is cognate with Sanskrit akṣi, Greek ὄψις (ópsis 'sight'), Latin oculus; the concrete image of facing something eye-to-eye grounds the meanings 'evident' and 'to reject'.
