The phrase я ошибся is past tense but doesn't include an л near the end. Are there any other examples of this phenomenon? I asked some native speakers and they couldn't think of any. One of them proposed that this might be a special property of the verbs that only have a form ending with -ся, but this isn't the case since the past tense for надеятся, смеяться, and улыбаться uses л.

2Other verbs that don't have "л" in the past form are грести, скрести, ушибить(ся). However, "л" is missing only in singular masculine forms.– stillenatJul 30, 2013 at 12:59

There are a number of verbs that do not take "-л-" to form past masculine forms.
Those are verbs that have the stem ending in -с, -з, -б, -г, -к, -р in the past tense. For example,
нести -> нёс, спасти -> спас, трясти -> тряс, везти -> вёз, ползти -> полз, лезть -> лез, грызть -> грыз, грести -> грёб, скрести -> скрёб, ошибиться -> ошиб-ся, ушибить(ся) -> ушиб-(ся), мочь -> мог, умереть -> умер
Note that "-л-" is missing only in masculine forms. Feminine, neuter and plural forms all take "-л-".
я/ты/она несла, спасла, лезла, гребла, ошиблась, могла etc. мы/вы/они несли, спасли, лезли гребли, ошиблись, могли etc.
The explanation for this that I could find is that in Old Russian, short participle forms (that in modern Russian are used for past tense) took gender endings -ъ(masculine), -а(feminine), -о(neuter).
писалъ - писала - писало, моглъ - могла - могло
Later the weak reduced vowel -ъ was dropped, and pronouncing consonant clusters like "-сл-, -зл-, -бл-, -гл-, -кл-, -рл-" at the end of a word became more problematic. "-л-" was often devoiced or hard to pronounce in words like *спасл, *могл, *умерл and was later dropped as well.
It didn't happen with feminine, neuter and plural endings because there was a vowel following "-л-".

+1: How about verbs with with stem ending in -х like высохнуть → высох?– YuryJul 30, 2013 at 15:07

@Yury Yes, you're right! There might be even more. The point here is, it's not easy to pronounce /l/ in final position after most fricatives and plosives. Jul 30, 2013 at 16:25

3There're also verbs, that have an opposite effect in them, they have the -л, but the final consonant of the stem disappears before this -л, for example: ел (ate), the stem is ед-; упал, the stem is упад-; сел. Jul 31, 2013 at 2:27
That can happen in verbs ending in stuff like -чь and -нуть.
Like беречь. (To take care of)
The masculine singular past tense is берёг.
But this -л comes back in the other forms, plural, feminine, and neuter.
I would say: я берегла, since I am female. I drop the ë and it becomes an e. And I add the л ending. :)

1Thanks. What are some -нуть verbs with past tense not involving л? Off the top of my head, the past tense forms of (под)черкнуть all involve л.– KCdMay 19, 2022 at 15:44

The verb “сохнуть”. My family, at least, in the dialect I speak (I’m from Uzbekistan) он сох, она сохла, оно сохло, они сохли May 24, 2022 at 12:32
