Spelling & Capitalization — I can spell common words accurately in short writing and use basic capitalization conventions.

Spanish spelling may seem challenging at first, but it is actually far more phonetic and predictable than English. This regularity is not an accident — it is the result of centuries of deliberate standardization. The Real Academia Española (RAE), founded in 1713, has worked continuously to keep Spanish spelling closely aligned with pronunciation. Understanding this history helps you appreciate why Spanish spelling rules are consistent and why mastering them is achievable with focused practice.

Unlike English, where the same letters can represent wildly different sounds (think "cough," "through," and "though"), Spanish maintains a near one-to-one relationship between letters and sounds. However, a few tricky areas remain — silent letters, accent marks, and capitalization conventions that differ from English. These are the gaps that this lesson addresses: How do you spell common Spanish words correctly and apply capitalization rules that may surprise you as an English speaker?

Spanish spelling rests on a set of foundational principles that, once internalized, make accurate writing almost automatic. These principles govern how sounds map to letters, when accent marks appear, and where capitalization differs sharply from English conventions. Let's break these down into five core ideas.

The diagram below maps the most commonly confused sounds in Spanish to the letters that represent them. Pay special attention to the areas where multiple letters converge on a single sound — these are the spelling danger zones that cause the most errors for Spanish 2 students.

Notice how each confusion zone involves only two or three letters, not the whole alphabet. The /b/ sound can be written as either b or v, and the /s/ sound (in Latin American Spanish) can appear as s, c (before e/i), or z. Meanwhile, the /k/ sound uses c (before a/o/u) or qu (before e/i). The strong throat sound (similar to English "h") can be written as j or g (before e/i). When you encounter a word with one of these sounds, pause and think about which letter is correct — context and memorization are your best tools.

Stress Rules and Accent Marks

Spanish has two default stress rules. If a word ends in a vowel, n, or s, the stress naturally falls on the second-to-last syllable (these are called palabras llanas). If a word ends in any other consonant, the stress falls on the last syllable (these are palabras agudas). Whenever a word breaks these default patterns, a written accent mark (tilde) is required to show where the stress actually falls.

Diacritical Accent Marks (Tilde Diacrítica)

Some one-syllable words carry accent marks not for stress purposes but to distinguish between two different words that are spelled the same way. These are called tildes diacríticas. For example, tú means "you" (subject pronoun), while tu means "your" (possessive adjective). Similarly, él means "he," while el means "the." These small marks change meaning entirely, so omitting them is considered a genuine spelling error, not just a cosmetic issue.

One of the biggest surprises for English speakers learning Spanish is how much less capitalization is used. In English, we capitalize days, months, languages, and nationalities. In Spanish, none of these are capitalized. The following diagram and table lay out exactly what is and is not capitalized.

Below is a short paragraph written by a student that contains several spelling and capitalization errors. We will walk through each correction step by step, explaining the rule that applies in each case.

Not all spelling errors are created equal. Some mistakes are more common — and more disruptive to communication — than others. The table below categorizes the most frequent errors that Spanish 2 students make, along with the impact of each mistake and a strategy for avoiding it.

The spelling and capitalization foundations covered in this lesson serve as the bedrock for more advanced writing skills you will develop in Spanish 3, AP Spanish, and beyond. Accurate spelling is not just about following rules — it signals literacy and care in formal writing contexts like essays, professional emails, and standardized exams.

On the AP Spanish Language and Culture exam, spelling and accent mark errors in the free-response sections can lower your score. Graders look for control of conventions as part of "language use." The habits you build now — double-checking b/v, remembering the silent h, applying stress rules for accents, and avoiding English-style capitalization — will directly translate into stronger performance on those high-stakes assessments. More importantly, they will make your written Spanish more natural and polished in any real-world context.
