INPUT ARTICLE: Article: Remove the -ir ending from the infinitive and replace it with the appropriate ending to talk about present actions. The -ir endings are -o, -es, -e, -imos, is, and -en. For example: Yo abro: I open. Tu abres: You [informal] open. El/ella/usted abre: He/she opens; you [formal] open. Nosotros abrimos: We open. Vosotros abris: You all [informal] open. Ellos/ellas/ustedes abren: They/you all [formal] open. When you're discussing an action that doesn't extend at all into the present, the preterite tense is appropriate. Depending on your subject pronoun, you will replace the -ir with -i, -iste, -io, -imos, -isteis, or -ieron. Yo abri: I opened. Tu abriste: You [informal] opened. El/ella/usted abrio: He/she/you [formal] opened. Nosotros abrimos: We opened. Vosotros abristeis: You all [informal] opened. Ellos/ellas/ustedes abrieron: They/you all [formal] opened. When you're talking about something that happens habitually, or that was interrupted, conjugate your verb in the imperfect tense. For an -ir verb, this means replacing the -ir with -ia, ias, ia, -iamos, iais, or -ian. Yo abria: I was opening. Tu abrias: You [informal] were opening. El/ella/usted abria: He/she was opening; you [formal] were opening. Nosotros abriamos: We were opening. Vosotros abriais: You all [informal] were opening. Ellos/ellas/ustedes abrian: They/you all [formal] were opening. In Spanish, the conditional tense is used to describe actions that might happen, or that are dependent on some other condition to happen. Regular -ir verbs are conjugated using the same endings as the imperfect tense, added to the end of the infinitive rather than the verb stem. Yo abriria: I would open [if]. Tu abririas: You [informal] would open [if]. El/ella/usted abriria: He/she/you [formal] would open [if]. Nosotros abririamos: We would open [if]. Vosotros abririais: You all [informal] would open [if]. Ellos/ellas/ustedes abririan: They/you all [formal] would open [if]. Add an ending to the full infinitive to conjugate regular -ir verbs in future tense, just as you did with the conditional tense. Use the endings -e, -as, -a, -emos, -eis, and -an. Yo abrire: I will open. Tu abriras: You [informal] will open. El/ella/usted abrira: He/she/you [formal] will open. Nosotros abriremos: We will open. Vosotros abrireis: You all [informal] will open. Ellos/ellas/ustedes abriran: They/you all [formal] will open.

SUMMARY: Use the present tense to describe actions currently happening. Switch to the preterite tense if the action happened in the past. Move to the imperfect tense if a past action continues to happen. Add the imperfect ending to the infinitive to express the conditional tense. Pick the future tense for talking about actions that will happen.

INPUT ARTICLE: Article: Sudden weight gain or weight loss could be a sign of any number of medical issues, but even if depression is not the cause, you should still consult a doctor. If you have noticed that your appetite has increased or decreased significantly, then be sure to talk to your doctor about this as well. This may be a symptom of depression, or it could indicate another underlying problem. You may also consider any risky behaviors that you have adopted as a symptom. This is especially true for men with depression. If you have recently started engaging in drug and/or alcohol use, unsafe sex, reckless driving, or dangerous sports, then this may indicate depression. Frequent crying paired with other symptoms could indicate depression, especially if you aren't sure why you're crying. Consider how often you typically cry and what makes you cry. For example, if you find yourself crying for no reason or over something trivial, such as spilling a cup of water or missing your bus, then this is a good indication that you may be depressed. Be sure to share this symptom with your doctor. Tearfulness, or frequent crying, is a common symptom of depression in teens. If you have frequent unexplained headaches or other pains, this is another good reason to consult a doctor. A medical condition may be to blame or the aches and pains may be due to depression. Physical pain is one of the more common and often overlooked signs of depression in men. If you are a man experiencing backaches, headaches, stomach problems, sexual dysfunction, or any other physical symptoms, be sure to tell your doctor. Elderly people often complain about physical problems over mental or emotional ones, and so depression may hide for a long time. Be aware of any physical changes, deaths of friends, and losses of independence that could trigger depression. You may also notice things like having trouble sleeping, or sleeping too much.

SUMMARY:
Keep an eye out for appetite changes. Note any risky behaviors. Consider how often or how easily you cry. Reflect on any mysterious aches and pains you have had.
