Sinalefa: Why Spanish Words Sound Joined Together
You can know every word in a Spanish sentence and still miss it when someone says it. One reason is that the spaces you see on the page do not always sound like separate breaks when people speak.
When one word ends in a vowel sound and the next begins with a vowel sound, those vowels can join in a single spoken syllable. This is called sinalefa. You may come across the term in poetry, where it matters for counting syllables, but the same kind of joining also happens in everyday speech.
Here are three examples. The ‿ mark shows where the vowel sounds can connect. It is just a pronunciation guide here; the words keep their normal spelling and spaces.
la‿escuela
the school
a + e: Notice the a at the end of la and the e at the start of escuela. You can move from one into the other without a separate beat between the words.
una‿idea
an idea
a + i: The final a meets the following i. Say the phrase slowly, then again with the vowels flowing together.
necesito‿ayuda
I need help
o + a: The o at the end of the first word connects with the a at the start of the next.
A pause or emphasis can keep the vowels separate, so you do not need to force a connection every time. I would start by listening for it. When a familiar phrase sounds like one long word, check whether two vowels are meeting across a word boundary.
Now imagine you are talking with a language partner about travel. Spain is somewhere you want to go. How would you say “I want to go to Spain”?

Once you have built the sentence, say it aloud. Look for places where one word ends in a vowel and the next starts with one. Try letting those sounds connect, then record yourself and listen back. Keep a comfortable pace and pay attention to how the words flow together.
