open something that is locked
To open something that has a lock, like a door or a car, by using a key, code, or card.
用法パターン：
to unlock [something]
よくある間違い：
Learners sometimes say *open the lock* when they mean *unlock the door* or *unlock the box*. Use *unlock* with the thing that has the lock (door, car, safe), not usually with the word *lock* itself.
類義語

|

make a phone or device usable
To enter a code, password, or use your face or finger so you can use your phone, tablet, computer, or another device.
用法パターン：
to unlock [a device/screen/account]
よくある間違い：

類義語
log in (Used more for accessing online accounts or computer systems, not usually for simply waking a phone screen.)

3
make resources or features available
To make money, help, or special features available so people can use them.
用法パターン：
to unlock [resources/options/features]
よくある間違い：
Learners may confuse this sense with the physical meaning and think *unlock* must always involve a real lock. In business, news, or tech, *unlock* is often used figuratively with words like *resources*, *funds*, *features*, and *opportunities* to mean *make them available*, not to open a physical lock.
類義語
release (Very close in meaning; slightly more general and common in formal and informal contexts.)
|
enable (Focuses more on making something possible or turning something on, especially in technical or software contexts.)
対義語
block (To prevent access to resources or features so they cannot be used.)
|
restrict (To limit how much something can be used or who can use it.)

reveal or bring out something hidden
To help show or use something that was hidden, like a secret, an idea, or someone’s talent or feelings.
用法パターン：
to unlock [potential/secrets/creativity/feelings]
よくある間違い：
Learners may take this meaning too literally and expect a real lock or key. Here, *unlock* is figurative and is often used with abstract nouns like *potential*, *secrets*, *creativity*, *memories*, and *emotions* to mean *help them come out* or *help people understand them*.
類義語
reveal (Focuses on making something known or visible; does not always carry the idea of enabling use or growth.)
|
unleash (Stronger and more dramatic; often suggests releasing powerful or intense forces or emotions.)
対義語
suppress (To keep feelings, abilities, or ideas hidden or held back instead of letting them come out.)
|
conceal (To hide information or feelings so they are not seen or understood.)
