|Conjugation:||Rule XIII: "e-ee" vocal doubling|
|Application:||-||Generally these rules apply to verbs that end on "elen", "eren", or "enen" (e.g. "spelen" => "sp-elen").|
|-||In the Singular I, II and III forms of the OTT (Present), in all forms of the OVT (Past), in the Voltooid Deelwoord, as well as in the Imperative the vocal "e" gets doubled. For strong verbs this applies only for the OTT (Present) and Imperative, as the other tenses are built strongly.|
|-||For elen/eren/enen verbs it is checked how many further vocals the verb has.|
If the verb only has one further vocal, then the "e" from elen/eren/enen does not get doubled, die accentuation remains short, e.g. "klapperen" => "kl-a-pp-eren" => "ik klapperde", not "ik klappeerde".
If the verb however does not have "one further vocal" (means, more than one or none at all), then the "e" from elen/eren/enen gets doubled, the accentuation becomes long, e.g. "decoreren" => "d-e-c-o-r-eren" => "ik decoreerde", not "ik decorerde".
Vocals, that are included in a non-separable verb prefix (e.g. "onteren" (ont-eren)), are not counted. In the case of "onteren" the verb by that does not have a further vocal, the "e" in "eren" gets doubled => "ik onteerde", not "ik onterde".
Note: The above rules do not match to 100%. For that reason, you can instruct Coniuno to build verbs explicitly against these rules by adding the respective verbs to one of the two lists "elen/eren/enen-short" and "elen/eren/enen-long".
