Resumen

Expressing feelings and attitudes in English becomes much easier once you master a simple but powerful structure: adjectives followed by infinitives. This combination allows you to describe how people feel about specific actions or situations, and it appears constantly in everyday conversations.

How do adjectives plus infinitives work?

This structure connects an adjective with the infinitive form of a verb (to + base verb) to describe a person's attitude or emotions. An important rule to remember: this pattern is used to describe people, not things [0:15]. The reason is straightforward — we use it to talk about someone's feelings toward something.

Here are some clear examples from the lesson:

  • He is happy to see you. [0:35]
  • They're ready to go. [0:48]
  • She's sad to hear the terrible news. [0:53]

Notice that every sentence follows the same pattern: subject + be + adjective + to + verb. The infinitive form always includes the preposition to before the base verb: to see, to go, to hear.

What are the most common adjective and infinitive combinations?

Not all adjectives work the same way emotionally. You can group them by the type of feeling they express [1:10].

Which adjectives express positive feelings?

  • Happy to — the most basic positive expression.
  • Pleased to — slightly more formal, similar to happy to.
  • Glad to — another warm, positive alternative.

Which adjectives express negative or mixed feelings?

For less cheerful emotions, you can use:

  • Sad to — expressing sorrow.
  • Disappointed to — showing unmet expectations.
  • Upset to — conveying frustration or distress.

What other useful combinations should you know?

Beyond positive and negative feelings, several adjectives paired with infinitives describe readiness, fortune, or fear [1:30]:

  • Lucky to and fortunate to — expressing gratitude for good circumstances.
  • Excited to — showing enthusiasm.
  • Afraid to — indicating fear or hesitation.
  • Prepared to and ready to — signaling willingness or readiness.

How are adjectives plus infinitives used in real conversations?

A role play in the lesson demonstrates how naturally these combinations appear in a workplace scenario [1:48]. Emma arrives at her new job and meets her colleague Manny. Their dialogue is full of practical examples:

  • "I'm excited to be here." — Emma expresses enthusiasm about starting her new position [2:18].
  • "I'm glad to hear that." — Manny responds positively to Emma's attitude [2:24].
  • "We are all happy to welcome you to the team." — Manny makes Emma feel included [2:34].
  • "I'm glad to help with anything you need." — Manny offers support using the same structure [3:04].

Pay attention to how the adjective changes the emotional tone of each sentence while the grammatical pattern stays exactly the same. Whether you feel nervous, excited, or glad, the structure remains consistent.

How can you practice this structure effectively?

The best way to internalize adjectives plus infinitives is to create your own sentences. Try completing these prompts with real situations from your life:

  • I am excited to...
  • I am ready to...
  • I am afraid to...
  • I am lucky to...
  • I am fortunate to...

Think about genuine feelings and real actions. For example: "I am excited to learn new grammar structures" or "I am afraid to speak in public." The more personal your sentences are, the easier it will be to remember this pattern.
