ניסה — to try

ניסה nisá, “try, attempt, test,” is pi'el, root נ־ס־ה, in the ל״ה class. Final ה disappears or changes before most endings, producing ניסיתי, ניסתה, ניסו, לנסות. Its two main frames are simple: an attempted action follows as an infinitive, while a thing sampled or tested is a direct object.

Modern Hebrew uses תנסו / ינסו for every plural gender. Dedicated feminine-plural תנסינה is (formal or literary). Unlike sound pi'el verbs, the forms ניסיתם / ניסיתן keep their stem stress in ordinary speech: nisítem / nisíten.

תנסה שוב; הפעם תלחץ על הכפתור הימני.

tenasé shuv; hapá'am tilkháts al hakaftór haymaní.

Try again; this time press the right-hand button. (to a man)

ניסינו הכול, אבל המחשב עדיין לא נדלק.

nisínu hakól, avál hamakhshév adáyin lo nidlák.

We tried everything, but the computer still won't turn on.

One spelling, two present-tense readings

The masculine and feminine singular present are both written מנסה. Pointing and stress separate them: masculine מְנַסֶּה menasé, feminine מְנַסָּה menasá. This is a central ל״ה pattern, not an irregularity unique to this verb; the same contrast appears in מחכה mekhaké / mekhaká. The pi'el ל״ה page compares the full class.

הוא מנסה להסביר לך למה זה חשוב.

hu menasé lehasbír lekhá láma ze khashúv.

He's trying to explain to you why it's important. (to a man)

היא מנסה להסביר לך, אבל אתה לא מקשיב.

hi menasá lehasbír lekhá, avál atá lo makshív.

She's trying to explain it to you, but you aren't listening. (to a man)

💡
Because ordinary Hebrew omits vowels, only syntax and agreement reveal which מנסה you are reading. The romanization marks the contrast directly: menasé masculine, menasá feminine.

Trying to do something

An attempted action follows ניסה as an infinitive: ניסה להתקשר, מנסה להסביר, ננסה להגיע. Hebrew does not insert a preposition corresponding to English at or with; the infinitive attaches directly.

ניסיתי להתקשר אלייך פעמיים, אבל הקו היה תפוס.

nisíti lehitkashér eláyikh pa'amáyim, avál hakáv hayá tafús.

I tried to call you twice, but the line was busy. (to a woman)

ננסה להגיע לפני שמונה, אבל אל תחכו לנו עם האוכל.

nenasé lehagía lifnéi shmóne, avál al tekhakú lánu im ha'ókhel.

We'll try to arrive before eight, but don't wait for us before eating.

ניסיתי לפתוח את הקובץ ולא הצלחתי.

nisíti liftóakh et hakóvets velo hitslákhti.

I tried to open the file and couldn't.

The frequent impersonal phrase שווה לנסות means “it is worth trying.” אין מה להפסיד “there is nothing to lose” often supplies the encouragement before תנסה / תנסי / תנסו.

אין מה להפסיד — שווה לנסות עוד פעם אחת.

ein ma lehafsíd; shavé lenasót od pá'am akhát.

There's nothing to lose—it's worth trying one more time.

Trying or testing a thing

When the complement is a thing rather than an action, ניסה is transitive. An indefinite item is bare; a definite item takes את. With food, “try” usually means taste or sample. With a method, product or device, it means test it in practice.

נסה את המנה הזאת; היא חריפה אבל ממש טעימה.

nasé et hamaná hazót; hi kharifá avál mamásh te'imá.

Try this dish; it's spicy but really tasty. (to a man)

ניסינו את השיטה החדשה במשך חודש והחלטנו להמשיך.

nisínu et hashitá hakhadashá beméshekh khódesh vehekhlátnu lehamshíkh.

We tried the new method for a month and decided to continue.

This direct-object frame differs from בדק “checked/examined.” ניסה את המכשיר means used the device experimentally to see how it worked; בדק את המכשיר means inspected or checked it. The actions can overlap, but their perspectives differ.

ניסיון, ניסוי and מנוסה

ניסיון has two everyday senses: an attempt and accumulated experience. Context separates ניסיון נוסף “another attempt” from ניסיון עבודה / ניסיון מקצועי “work/professional experience.” Someone with experience is מנוסה menusé / menusá, the lexicalized pu'al adjective “experienced.”

אין לי הרבה ניסיון בעבודה עם ילדים, אבל אני לומדת מהר.

ein li harbé nisayón ba'avodá im yeladím, avál aní lomédet mahér.

I don't have much experience working with children, but I learn quickly. (f. speaker)

זה היה הניסיון השלישי שלנו לפתור את הבעיה.

ze hayá hanisayón hashlishí shelánu liftór et habe'ayá.

That was our third attempt to solve the problem.

ניסוי is an experiment or trial designed to test something, especially in science, medicine and engineering: ניסוי קליני “clinical trial,” ניסוי מעבדה “laboratory experiment.” It is not a synonym for personal experience.

הניסוי הקליני יתחיל בחודש הבא בבית החולים.

hanisúy hakliní yatkhíl bakhódesh habá bevéit hakholím.

The clinical trial will begin next month at the hospital. (medical/technical)

💡
Ask whether somebody attempted something or whether researchers experimented. The first is ניסיון; the second is ניסוי. Only ניסיון also means accumulated experience.

ניסה is not נסע

Bare ניסה “he tried” and נסע “he traveled by vehicle” differ by one written letter and belong to different binyanim and roots. Pointed נִיסָּה is pi'el נ־ס־ה; נָסַע is pa'al נ־ס־ע. Their infinitives make the difference unmistakable: לנסות lenasót versus לנסוע linsóa. The נסע reference card supplies its separate paradigm.

הוא ניסה לנסוע לעבודה, אבל הרכב לא הניע.

hu nisá linsóa la'avodá, avál harékhev lo henía.

He tried to drive to work, but the car wouldn't start.

Key Takeaways

  • ל״ה produces ניסיתי, ניסתה, ניסו and the ־וֹת infinitive לנסות.
  • Present מנסה is menasé masculine or menasá feminine; spelling alone does not distinguish them.
  • An attempted action is an infinitive: ניסה להתקשר. A sampled or tested thing is a direct object: ניסה את המנה.
  • ניסיון means attempt or experience; ניסוי is an experiment or trial; מנוסה means experienced.
  • Keep ניסה / לנסות apart from נסע / לנסוע.

  • Pi'el ל״ה: ניסה, חיכה, קיווה, ניקהB1The third root letter never surfaces as a ה. It shows up as a yod in most of the past, as ־ה or ־ות elsewhere, and disappears entirely before ־וּ — and the two present-tense singulars end up spelled identically, separated only by a vowel nobody writes.
  • Verbs That Take an Infinitive (רוצה, אוהב, מנסה, מתחיל)A1The first two-verb sentence a beginner can build: one conjugated verb, then an infinitive that never changes for anything. The whole pattern turns on a single question — is the second action done by the same person as the first? If it is, use the infinitive; if it is not, Hebrew switches to ש plus a finite verb.
  • נסע — to travel, to driveA2Conjugate נסע, preserve its disappearing initial נ in the future, and choose the right Hebrew motion verb and preposition.
  • ל״ה Across the BinyanimB2Hebrew's largest weak class, and the tidiest: whatever binyan you are in, a ל״ה verb takes the same six endings. Learn them once and קניתי, נראיתי, ניסיתי, הראיתי and השתניתי stop being five separate problems.
  • בישל — to cookA2Conjugate בישל, hear its initial b/v alternation, and choose the specific Hebrew verb for each cooking method.
  • חיכה — to waitA2Conjugate ל״ה חיכה and use ל־, a bare duration, or a ש־ clause for the three things that can follow it.
