1. Adverbs of Time

Adverbs tell us when, how often, or for how long an action happens. They are essential for situating events in time.

Worked Example:

Yesterday, I visited the agricultural exhibition at Mlimani City. The farmers already displayed their crops before the official opening. The event currently showcases modern farming techniques. Tomorrow, the workshop will demonstrate irrigation methods.

2. Prepositions of Time

Prepositions indicate relationships between nouns and other words, specifically temporal relationships.

Worked Example:

In December 2023, many students completed their Form 6 examinations. The exams took place on 4th December and continued until 22nd December. Students had been studying since August. During the examination period, they remained focused.

3. Conjunctions for Sequencing Events

Conjunctions connect words, phrases, or clauses. They are crucial for creating complex sentences that show relationships between events.

Time Conjunctions

• Before — "The documentary aired before the news broadcast."
• After — "After the rain stopped, we continued our journey."
• When — "When the sun sets, the market vendors pack their goods."
• While — "While the teacher explained the lesson, students took notes."
• As soon as — "As soon as the bus arrived, passengers boarded."
• Until — "We waited until the ferry crossed the lake."
• Since — "Since the drought began, water scarcity has increased."

Purpose and Result Conjunctions

• So that — "She saved money so that she could open a small shop."
• Because — "The crop failed because there was insufficient rainfall."
• Although/Even though — "Although the road was rough, we reached our destination."

Worked Example:

The research team conducted a survey before the rainy season began. After collecting data from 200 households, they analyzed the results. When they finished, they presented their findings. Since the study began, several farmers have adopted new techniques. Although challenges existed, the project continued until its completion.

Using Specific Verbs and Adjectives

To make your descriptions more precise, pair adverbs with appropriate verbs:

• Past: conducted, investigated, observed, recorded, discovered
• Present: examine, monitor, assess, implement, collaborate
• Future: will undertake, are planning to, expect to, aim to

Worked Example (Documentary-style narration):

"In 2023, researchers from Sokoine University of Agriculture conducted a comprehensive study on cassava farming in Morogoro. They visited several villages during the harvest season. The team recorded significant findings before publishing their report. Currently, they are implementing recommendations to improve crop yields. By next year, they expect to expand their research to coastal regions."

In Tanzania, you will frequently use these grammatical structures when narrating events in everyday situations. For example, when explaining to a mteja (customer) at your family's duka la mboga (vegetable shop) in Kariakoo, you might say: "I already stocked fresh tomatoes this morning. The supplier arrived before 7 a.m. Since the price increased yesterday, I will adjust the rates tomorrow." Using correct adverbs, prepositions, and conjunctions helps you communicate clearly about past deliveries, present stock, and future plans—essential skills for small business management in Tanzanian markets.
