Past participle agreement
The l-participle (l-ové příčestí) is the main verb form used to talk about the past in Czech. It acts like an adjective, meaning its ending changes to match the gender and number of the subject.
How It Works
Because the participle agrees with the subject, saying "I did it" inherently reveals your gender: a man says dělal jsem to, while a woman says dělala jsem to.
Important Spelling Rule:
In the plural, the masculine animate ending -li and the feminine/masculine inanimate ending -ly are pronounced exactly the same (they are homophones). The difference is purely a spelling rule, but getting this agreement right in writing is one of the most strictly tested grammar rules in Czech! Note the mixed-gender rule: if a plural subject contains even one masculine animate noun (e.g., a man and a woman), the spelling defaults to the masculine animate -li. Additionally, be careful not to confuse the neuter plural ending -la with the feminine singular ending -la—they look identical but represent different genders and numbers.
No 3rd Person Auxiliary:
Unlike English, which uses auxiliary verbs in the 3rd person ("he has done", "he was doing"), Czech uses the bare participle for the 3rd person past. Never add "je" or "jsou" to a 3rd person past tense sentence.
Reflexive Verbs in the 2nd Person:
When using reflexive verbs in the past tense for the 2nd person singular (you), the auxiliary verb jsi merges with the reflexive pronouns se or si to form ses or sis. For example, instead of saying "smál jsi se", you must say smál ses (you laughed), and instead of "koupil jsi si", you say koupil sis (you bought for yourself).
Second-Position Clitics:
Past tense auxiliary verbs (jsem, jsi, jsme, jste) and reflexive pronouns (se, si, ses, sis) are unstressed words called clitics. They must always occupy the second position in a clause. For example, you should say Včera jsem to dělal (Yesterday I did it), not "Včera to dělal jsem".
Formal "You" (Vykání):
When addressing a single person formally using polite you, the auxiliary verb is plural (jste), but the l-participle remains singular to match the person's gender. For example, to a man you say Dělal jste to? and to a woman Dělala jste to?.
Negative Past Tense:
To form the negative past tense, the negative prefix ne- attaches directly to the l-participle, never to the auxiliary verb. For example, you must say Nedělal jsem to (I didn't do it), and never "Nejsem dělal to".

Common Mistakes
Using a 3rd-person auxiliary verb in the past tense.
Petr je psal dopis.Petr psal dopis.In the 3rd person (he/she/it/they), the past tense uses only the l-participle. Do not add 'je' or 'jsou' like you would in English ('he has written' or 'he was writing').
Using the neuter plural ending for 'děti' (children).
Děti si hrála.Děti si hrály.Although the singular word 'dítě' (child) is neuter, its plural form 'děti' is grammatically feminine. Therefore, it must take the feminine plural ending '-ly', not the neuter '-la'.
Female speakers defaulting to the masculine dictionary form for themselves.
Different MeaningByl jsem tam.Byla jsem tam.The l-participle must agree with the speaker's gender in the 1st person. Female speakers must use the '-la' ending.
How It Connects
Learn This First
To form and use the past participle correctly, you must first understand how to identify the subject of the sentence (nominative case) and its gender (masculine, feminine, or neuter), as the participle's ending depends on these factors. Additionally, since the past tense is a compound tense, you need to know the present tense of the verb 'být' which acts as the auxiliary verb.

Level 2 - Present conditional
The l-participle is also the core verb form used alongside conditional clitics (bych, bys, by) to create the conditional mood.
Level 3 - -i / -yPast-tense Plural Gender Endings
This pattern specifically focuses on the tricky orthographic distinction between -li and -ly in the plural l-participle.
Level 3 - Agreement with coordinated subjects
