you can always us this in your function file

//This function changes the text wherever it is quoted
function change_translate_text( $translated_text ) {
	if ( $translated_text == 'old text' ) {
	$translated_text = 'new text';
	}
	return $translated_text;
}
add_filter( 'gettext', 'change_translate_text', 20 );

so you would have

//This function changes the text wherever it is quoted
function change_translate_text( $translated_text ) {
	if ( $translated_text == 'by' ) {
	$translated_text = 'par';
	}
	return $translated_text;
}
add_filter( 'gettext', 'change_translate_text', 20 );
