Hindi ability with sakna: can, cannot and could

01 / Understand

Separate the action from the ability

The action tells us what is possible: read, swim, understand, or come. The following ability expression tells us whether the subject can perform that action. In पढ़ सकता हूँ, the stem पढ़ does not take the habitual ending ता, the ending used for routines. The agreement appears on सकता, followed by the appropriate auxiliary, a form of होना “be” such as हूँ.

Think of an unfamiliar sign. A person may know Hindi but be unable to read that particular sign because the print is too small. A sentence with सकना is therefore not always a permanent claim about a learned skill. Give enough context to make the practical meaning clear.

A language skill can also be expressed with आना and a person marked with को, as in मुझे हिंदी आती है “I know Hindi.” That is useful background for understanding why the English word can does not have one universal Hindi translation. The lesson’s ability construction is most useful when you name a possible action: reading this sign, coming tomorrow, or helping with a task. Do not replace every occurrence of know with सकना. Identify whether you mean knowledge of a fact, a learned skill, or the possibility of performing a particular action in the present situation.

Use the stem, not the infinitive

The dictionary form, or infinitive, तैरना means “to swim.” Before the ability expression, use तैर, without ना. Keeping the infinitive produces the wrong combination in this construction. Contrast this with wanting, where an infinitive normally remains before a form of चाहना.

A compound expression such as मदद करना “help” keeps its noun and uses the stem कर: मदद कर सकता हूँ. Removing करना entirely would leave the construction incomplete. Learn the full action phrase, then change only the part required by the grammar.

03 / Understand

Match agreement to the person

Use सकता with masculine singular agreement, सकती with feminine agreement, and सकते with masculine plural or respectful agreement. The auxiliary still distinguishes first person singular, familiar you, and plural or respectful forms. Both words belong in the check.

For a woman addressed respectfully, आप पढ़ सकती हैं combines feminine agreement with the respectful auxiliary. A feminine form does not automatically require singular है. The social form of address and gender agreement contribute different information, just as they do in the ordinary habitual construction.

The same respectful pronoun can occur with different gender agreement according to the person addressed. Compare आप कर सकते हैं for masculine agreement with आप कर सकती हैं for feminine agreement. In both, the final auxiliary remains respectful. The object of doing has no role in this contrast. To practice accurately, write a small role card describing the listener before building the sentence. Then switch the role card while leaving the action unchanged. This avoids using a masculine form as an unexplained default in a question explicitly addressed to a woman.

04 / Understand

Deny the ability without changing the action

The common negative नहीं denies the ability. You can encounter it before the action or between the action and the ability verb; the examples here use the latter when emphasizing inability. Read the whole sentence rather than declaring every alternative position ungrammatical.

Do not use मत for an ordinary statement that you cannot do something. A prohibition tells another person not to act; inability states that an action is not possible for the subject. In a practical conversation, add the reason in a separate sentence if it matters.

05 / Understand

Ask about possibility and permission

A question such as क्या मैं यहाँ बैठ सकता हूँ? “Can I sit here?” can seek permission even though its grammar is built around possibility. The relationship and setting make that use understandable. It is a request, not evidence that the speaker lacks the physical ability to sit.

Use initial क्या for a yes or no question. In an information question, कहाँ asks where an action is possible. Keep a location phrase such as इस कमरे में together. Before a postposition (a word such as में that follows its noun), the demonstrative, a pointing word, changes from its direct form यह to its oblique form इस, even though the ability phrase itself is unchanged.

A permission question is interpreted socially. Asking whether you can sit in a room does not establish that the listener has authority to grant permission. In an unfamiliar setting, identify the person responsible or follow an instruction already given. The lesson teaches the wording of a request, not a rule about who may decide. In a language exchange, compare the same question in two contexts: a guest asking a host for permission and an injured person asking whether a chair is usable. The grammatical form can remain similar while the practical question changes.

06 / Understand

Move the possibility into another time

The auxiliary can locate a general ability in the past: सकता था or सकती थी. A future form such as सकूँगा says “I will be able to,” with masculine agreement. Avoid attaching future endings to both the main verb and the ability verb.

Perfective forms such as सका or सकी, which present an event as completed, can describe a realized possibility in a particular situation. A completed transitive verb, one that takes an object, normally puts ने after its subject, but with सकना you do not add ने, even when the main action is transitive. The construction has subject agreement. Keep general past ability and success on one occasion distinct in the surrounding context.

Past general ability and success on a particular occasion can be separated by the time frame. A childhood ability is naturally described with a habitual ability expression and a past auxiliary. A report about finally reading a difficult word can use a perfective form. The latter does not necessarily imply that the person had a permanent skill before the event. It reports what was possible or achieved in that situation. When English says could, ask whether it describes an established capacity or one occasion; do not select the Hindi form from that English word alone.

07 / Understand

Distinguish ability from managing to succeed

The auxiliary पाना often emphasizes whether circumstances allowed someone to manage an action. सकना gives a broad ability or possibility reading. Their uses overlap, so do not reduce them to an absolute distinction between an internal skill and an external obstacle.

In the challenge, identify the action stem before looking at the endings. Then check subject, agreement, tense, and the intended kind of statement. Reconstruct a missed example with a different subject. A correct answer should be defensible by these features, not by how similar it looks to the preceding example.
