Traditionally Basque verbs are cited using a non-finite form conventionally referred to as the participle (although not all its uses are really participial). Other non-finite forms can be derived from the participle, as will be seen in a later section. When the verb possesses synthetic finite forms, these are based on an ultimate stem (called the "basic stem" here) which is normally also present in the participle. For example, the verb 'come' has the basic stem "-tor-" from which are derived both the participle (with the non-finite prefix "e-" and the participle suffix "-i") and the finite present stem "-ator-" and non-present stem "-etor-".
