mikäli / jollei / ellei

Formal Conditionals

Level 5

Mikäli = Formal 'if' (provided that).
Ellei / Jollei = Formal 'if not' (unless).

How It Works

In advanced Finnish, register matters. While jos is the universal word for 'if', formal contexts often prefer mikäli, ellei, and jollei.

1. Mikäli (If / Provided that)
This is an uninflected particle. It is often used when a condition is a prerequisite or in the phrase mikäli tiedän ('as far as I know').

2. Ellei and Jollei (Unless / If not)
These are the formal equivalents of jos ei. They are formed by combining a conditional element with the negative verb. Because they are verbs, they must conjugate:

  • ellen / jollen (if I don't)
  • ellet / jollet (if you don't)
  • ellei / jollei (if he/she/it doesn't)
  • ellemme / jollemme (if we don't)
  • ellette / jollette (if you all don't)
  • elleivät / jolleivät (if they don't)

Jollei is a variant of ellei; both are standard and interchangeable, though ellei is slightly more common.

3. Sentence Structure
After ellei or jollei, the main verb appears in the connegative form (the stem without an ending), just like after the standard negative verb ei.

Examples (5)

  1. Mikäli sää sallii, ottelu pelataan ulkona.

    Provided the weather permits, the match will be played outdoors.

    Word by Word: If weather permits, match is-played outside.

    Mikäli is used here to set a formal condition, similar to 'provided that'.

  2. Ellei toisin ilmoiteta, kokous alkaa kello yhdeksän.

    Unless otherwise notified, the meeting starts at nine o'clock.

    Word by Word: If-not otherwise is-notified, meeting starts clock nine.

    Ellei is the 3rd person singular form, agreeing with the impersonal context of the notification.

  3. Jollette te tee päätöstä pian, tilanne vaikeutuu.

    If you (plural) do not make a decision soon, the situation will become difficult.

    Word by Word: If-not-you you make decision soon, situation becomes-difficult.

    Jollette is the 2nd person plural form, agreeing with 'te' (you all).

  4. Mikäli tiedän, hän ei ole vielä saapunut.

    As far as I know, he has not arrived yet.

    Word by Word: As-far-as I-know, he not is yet arrived.

    Mikäli is commonly used in the fixed phrase 'mikäli tiedän' (as far as I know).

  5. Lähdemme heti, ellen saa uusia ohjeita.

    We will leave immediately unless I receive new instructions.

    Word by Word: We-leave immediately, if-not-I get new instructions.

    Ellen is the 1st person singular form, agreeing with the implied 'minä'.

Common Mistakes

  • Using the 3rd person 'ellei' for all subjects.

    Ellei minä tule, aloittakaa ilman minua.
    Ellen tule, aloittakaa ilman minua.

    Ellei is a verb and must be conjugated. For 'minä' (I), you must use 'ellen'.

  • Double negation (adding 'ei' after 'ellei').

    Ellei hän ei tule ajoissa...
    Ellei hän tule ajoissa...

    The 'ei' (not) is already built into the word 'ellei'. Adding another 'ei' is redundant and grammatically incorrect.

  • Using 'mikäli' in casual conversation.

    Different MeaningSoita minulle, mikäli ehdit.
    Soita minulle, jos ehdit.

    While grammatically correct, 'mikäli' sounds overly stiff and robotic in casual speech. Use 'jos' with friends.

Learn This First

To understand formal conditionals, you first need to be comfortable with the basic 'if' conjunction (jos) and how the negative verb (en, et, ei...) functions, as 'jollei' and 'ellei' are contracted forms of the negative verb used in conditional contexts.
