Practical writing, correspondence, speaking and communication guides.
Write the recipient’s name and full mailing address in the center of the envelope’s front. Put your return address in the upper-left corner, then place the stamp in the upper-right corner. Keep the writing legible, leave clear space around the stamp and addresses, and check the address against your source before sealing or mailing.
To write a recommendation letter, confirm what the recipient needs, collect two or three specific examples of the person’s work, and organize the letter around a clear endorsement. Introduce your relationship, explain the person’s relevant strengths, prove them with brief examples, and close with a confident recommendation and your contact information. Check the required format before sending.
Share Focus Status means your iPhone can tell people in compatible apps, especially Messages, that your notifications are currently silenced by a Focus such as Do Not Disturb, Work, or Study. It does not show your notifications, messages, location, or exact activity. Contacts may still be able to notify you for urgent matters.
IRL means “in real life.” People usually write or say it as the letters I-R-L, especially in informal texts, direct messages, and online chats. It distinguishes an in-person or offline experience from something that happens online or in a digital space. In a work or learning message, treat IRL as casual shorthand and use “in person” for formal writing.
IDEK means “I don’t even know.” People use it in texts, group chats, and social posts to show confusion, disbelief, or mild frustration. Read the message around it to judge the tone. It fits casual conversation, but spell out your meaning in work, school, or other formal communication.
S/O most commonly means “significant other,” referring to a spouse, partner, or other romantic life partner. In workplace or online messages, S/O may also mean “shout-out,” “sign-off,” or “special order.” Check the surrounding words, the sender, and the message purpose before choosing a meaning.
On Facebook, a poke is a lightweight alert: the person you poke receives a notification. It does not include a written message or carry one fixed meaning. Someone may use it as a casual hello, a prompt to interact, or a playful exchange. Only the sender can tell you what they intended.
HMU means “hit me up.” In a text, chat, or social post, it is a casual invitation to contact the sender—usually by messaging, calling, or replying later. Read the surrounding sentence to confirm the timing and purpose. In formal work or school communication, use “contact me” or “message me” instead.
